Mounting of the Pillow BlocksNormally for the support of a shaft it is necessary as a rule to use a fixed and a floating bearing. Thefloating bearing permits expansion of the shaft due to thermal growth. DODGE HFO, HFOE and HFOUpillow blocks are designed and fabricated as either expansion or non-expansion bearings. It is notnecessary to insert spacer rings for either the expansion or the non-expansion bearings.

InspectionInspect the shaft. Make sure it is smooth, straight, clean and conforming to the correct dimensionaltolerances of the drawing. Inspect all the parts prior to assembly.

Adapter Mounted Units.

Fixed Bearing (Non-Expansion)1) Install the non-expansion bearing unit first. Apply a coating of light oil to the area where the adapter

will sit on the shaft.2) Measure the internal clearance of the bearing before mounting. Place the bearing in an upright

position as shown in Fig. 1. Seat the inner ring and roller elements by pressing firmly on the innerring bore while rotating the inner ring a few times. Position the roller assemblies so that a roller is atthe top most position on both rows (12:00 o’clock). Using a feeler gauge, measure the clearance forboth sides by inserting as far as possible and sliding over top of roller. (See Fig. 1) Write down themeasured clearance value for use in step 3 d .

Note: Do not rotate bearing rings when moving feeler between roller and outer ring.

Figure 1Checking Bearing Radial Clearance

3) Install the pillow block and bearing parts in the following sequence:a) Slide the inboard end cover (item 7 on sketch A) on the shaft first with the piloted side facing the

end of the shaft. For HFOE this cover has the slots for passage of the oil ring. For HFO thiscover is plain since the oil ring is mounted on the opposite side. Then slide one of the endcovers gasket over the shaft and placed next to the end cover.

b) Slide the left side labyrinth ring (item 1 on sketch A) on the shaft with the large OD facing theend of the shaft. Then if installing an HFOE unit slide the oil ring on the shaft and position it inthe proper groove on the labyrinth ring.

c) Slide the adapter on the shaft with the threaded end facing the end of the shaft. Locate theadapter at the proper location on the shaft. Apply a coat of light oil (32cSt) to the OD of theadapter sleeve. Do not use grease. Install bearing on the adapter sleeve.

Double row spherical roller bearings with tapered bore are properly mounted on the shaft when thecorrect reduction in radial play is achieved. To facilitate this procedure it is recommended to usehydraulic nuts and sleeves equipped with hydraulic features. d) Locknut and Lockwasher. Slide the lockwasher on the sleeve, then thread the locknut on the

threaded adapter sleeve. Tighten locknut first by hand then using a spanner wrench. Lighttapping with a hammer may be necessary to achieve proper tightening. Tighten until the properclearance reduction is achieved. See Table 1a. Remember that the bearing position will shiftaxially inboard approximately 17 times the reduction of radial clearance shown on Table 1a.Bend one tang of the lockwasher on the slot of the nut. If necessary tighten, not loosen, locknutto allow prong to fit in nut. Tightening of the bearing on the shaft can also be achieved using anhydraulic nut.

e) After properly securing the bearing to the shaft, slide the right side labyrinth ring (item 4 onsketch A) on the shaft against the adapter sleeve. At this time, if installing HFOE units drill andtap the shaft with M8 holes for set screws to axially secure the labyrinth rings to the shaft if thelabyrinths have a 10 MM drilled hole. For HFO and HFOE with drilled and tapped holes dimplethe shaft to a depth of 4 MM and using proper setscrews tighten the screws to lock the labyrinthrings. While tightening the setscrews push on the labyrinth ring in the direction of the bearing sothat a seal is formed between the labyrinth face and the contacting member. If installing an HFOunit slide the oil ring on the sleeve and locate in the appropriate groove.

f) Slide the bottom half of the housing under the bearing, align and hand tighten the mountingbolts to the frame. Place the top half of the housing over the bearing. At this time insert thetapered pins and tap tightly into the tapered holes using a plastic mallet. Tighten the taper pinslocknut over the lockwasher. Bolt the cap securely to the bottom half. On HFOE the cover boltstighten onto the bottom half of the housing. For HFO four bolts and nuts must be used to securethe top half to the bottom half.

g) Slide the second gasket on the shaft.h) Slide the final end cover over the shaft and bolt both the inboard and outboard cover to the

housing.i) For HFOE only, screw in Oil Ring Pin (item 7 on sketch A). This pin prevents bouncing of the oil

ring. HFO do not use an oil ring pin.j) Check one more time for the mounting location of the HFOE or HFO housing. Do not fully

torque the housing to the frame at this time. Full torque will be applied after the floating bearingis mounted.

Expansion BearingThe same procedure used to mount the Non-Expansion bearing is used to mount the Expansion bearing.During step d) check that the housing aligns with the mounting holes of the frame and that the bearing sitsin the centre of the housing.

After completing steps a-j above for the expansion bearing, proceed to tighten all the bolts that fasten thehousings to the frame using the torque values specified on Table 2.

Check misalignment on each pillow block by inserting a feeler gauge between the labyrinth sleeve OD andthe bore of the end cover. Insert the feeler gauge at 12:00 o’clock, at 6:00, 3:00 and 9:00 o’clock. Thereadings at the two positions must be within 0.1 and 0.2 mm. If the readings exceed these values loosenthe base bolts and realign the housing . Shimming may be necessary.

Direct Mounted Bearings

For direct mounted bearings it is not necessary to measure the internal clearance of the bearing. It ishowever necessary to check the markings on the bearing faces to insure the correct bearing is beinginstalled. It is however important to verify the shaft diameters. Mount all components in the followingorder:

For BF and BL (Shaft running through the covers)1) Slide the inboard cover on the shaft with the pilot toward the end of the shaft.

2) Slide the first gasket onto the shaft and place adjacent to the inboard cover.

3) Slide the large bore labyrinth on the shaft. For the HFO the serrations on the OD must be away fromthe shaft end. For the HFOE the large OD must be away from the shaft end. Normally theselabyrinth rings rest against the shaft shoulder. For the HFOE insert the oil ring over the labyrinth ringin the appropriate groove.

4) Heat the bearing in an oil bath at 100 degrees centigrade, then slide on the shaft. Hold against theface of the labyrinth until the bearing has cooled sufficiently not to move away from the labyrinth ring.

5) For the HFO insert the small bore labyrinth ring on the shaft and slide against the face of the bearing.

For the HFOE insert the lockwasher and then thread the locknut on the shaft until tight against theface of the lockwasher.

6) Slide the bottom half of the housing under the bearing, align and hand tighten the mounting bolts tothe frame. Place the top half of the housing over the bearing. At this time insert the two taper dowelsover the cap and base and using a plastic mallet tap down tightly. Tighten the nuts over thelockwashers. Bolt the cap securely to the bottom half. On HFOE units, the cover bolts run into thebase. On HFO, the cover bolts run through throughbores and nuts are used to clamp.

7) Slide the second gasket over the shaft and against the housing.

8) Slide the outboard cover on.

9) Tighten the bolts both on the inboard and outboard covers to the prescribed torque for the boltspecifications shown on Table 2.

10) For the HFOE screw in the oil ring pin. (item 4 on sketch E)

11) Tighten all the base mounting bolts to the torque values shown on Table 2.

12) Check misalignment on each pillow block housing by inserting a feeler gauge between the labyrinthsleeve OD and the bore of the end cover. Insert the feeler gauge at 12:00 o’clock and at 9:00o’clock. The readings at the two positions must be within 0.1 and 0,2 mm. If the readings exceedthese values loosen the base bolts and realign the housing . Shimming may be necessary.

For AL and AF options (End closure)Follow the same procedures 1-4 listed above for BL and BF options. Then continue as follows:a) For HFO install the short labyrinth ring, then the lockwasher and locknut. For the HFOE install the

locknut and lockwasherb) Slide the second gasket over the shaft and against the housing.c) Slide the outboard closed end cover on.d) Tighten the bolts on the inboard cover and on the outboard closed end cover to the prescribed

torque shown on Table 2.e) Tighten all the base mounting bolts to the torque values shown on Table 2.f) Check misalignment on each pillow block housing by inserting a feeler gauge between the labyrinth

sleeve OD and the bore of the end cover. Insert the feeler gauge at 12:00 o’clock and at 9:00o’clock. The readings at the two positions must be within 0.1 and 0,2 mm. If the readings exceedthese values loosen the base bolts and realign the housing . Shimming may be necessary

Sketches E and F show pictorially the way direct shaft mounted HFOE units look like in cross section afterbeing properly mounted. Sketches G and H show the way direct shaft mounted HFO units look like after beingproperly mounted.

Due to the axial expansion capability of the floating bearing it is possible to compensate for thermal shaftgrowth and length variations due to mounting inaccuracies or measurements. The expansion capability isguaranteed by the internal workmanship of the bearing seat to F6 tolerance for HFO and G6 for HFOEand HFOU units.

The expansion capability of the HFO, HFOE and HFOU bearings are shown on Table 1b.

548 20*This value can be obtained if the pillow block is shifted completely to one side relative to the bearing.Normally the bearing is mounted centered in the pillow block permitting only half this expansion value inboth directions.

MaterialsThe pillow blocks are produced with GG25 grey iron. Upon request it is possible to make the pillow blocksfrom other types of grey iron, from ductile iron or from steel.

SealsDue to possible problems with positive contact seals due to friction and wear HFO, HFOE and HFOUincorporate non-contacting labyrinth seals. The labyrinth seals used work extremely well under normalfunctional requirements and normal loads. For harsher conditions, for example in ambients particularlyaffected by dust and dampness, in the presence of large quantities of dirt etc., the effectiveness of thesealing system can be improved by injecting thru the grease fitting in the pillow block cover heavy greaseof NLGI 3 or 4 consistency.

To carryout this operation, for the HFOE’s just pump in NLGI 3 or 4 consistency grease. HFO’s normallycome equipped with a plastic plug inserted in the drain hole of the annular ring groove of the cover. Thisplug is removed under normal conditions. When this additional grease dam protection is desired then theplastic plug must be left in the annular groove return drain hole. The plug prevents grease to be pumpedinto the oil sump. The HFOE’s by design do not have an oil drain hole.

LubricationThe lubrication of the spherical roller bearings in HFO and HFOE pillow blocks is done with oil via an oilring. The oil ring rests on a sleeve with the lower part submerged in the oil found in the sump of the pillowblock. When the shaft turns it drags the oil ring with it at a lower rpm. The oil ring drags with it oil to thetop dumping it on the bearing. The oil drains back into the sump via an opening in the cover. The sumpdimensions are such to guarantee, via an optimum oil level, perfect lubrication of the bearing. In thelower part of the housing the oil cools, depending on the ambient temperature, before re-circulating. Thissystem of lubrication permits higher RPM’s . Because of the oil ring it is possible to maintain a largedifferential between minimum and maximum oil sump level. Therefore the lapsed time between oil refillsis extended. Oil level at start-up should be set at maximum.Oil fill for both HFO and HFOE are shown on Table 2.

The oil level indicator provided can be mounted in any of the four drilled and tapped holes found on thecovers. The drilled and tapped holes not utilised may be used for drains when changing oil. The oil level“min” and “max” shown on Table 2 must be marked on the sight gauge.

Oil SelectionDue to the high speeds that HFO, HFOE and HFOU are normally used at, it is recommended to useeither a mineral oil or one of the new synthetic oil. Both type of oils should incorporate additives againstageing, anticorrosion agents and antifoaming agents. The most important parameter of the oil is itsviscosity which is very dependent on the service temperature. Find below some recommendations for theselection:

Temperature Viscosity necessary at 50° C.(122°F)Service conditions normal From 40 to 70 cStambient temperature 0° to 25° CSpace volume not less than 40 m3

Normal air circulation

Service temperature slightly more From 70 to 100 cStelevated (30° to 50° C)Space more confinedwith less air circulation and some warming due warm gases

Higher oil viscosity must be selected when operating conditions are less favourable due to heat or whenthe loading conditions are such that the ratio of Fa/Fr is >e(Fa is the axial load on the bearing and Fr isthe radial load on the bearing)At elevated speeds, when the RPM is greater than 70% of the catalog rated speed, lower oil viscositymust be selected due to high heat generated by the churning oil. At low speeds, below 20% of catalograted speed the oil viscosity at operating temperature should not be below 100 cSt. At these low speedsan oil with viscosity ranging from 220 to 3320 cSt at 40 degrees C is an acceptable oil to use.

Limiting SpeedsDODGE type HFO, HFOE and HFOU pillow blocks, thanks to their type of lubrication are particularlysuited for service conditions with high speeds. The limiting speeds recommended by the bearingmanufacturers and shown in their catalogs can be obtained under the following conditions:

• Loads principally radial, such that the axial load is less than 20% of the radial load.• The equivalent load at operating speed will yield an L10 life greater than 50,000 hours of service.• Cooling of the oil guaranteed via the normal circulation of ambient air around the pillow block area• Self-aligning bearings are being used with internal clearance of C3.

When the limiting speed of the bearing is being reached it is recommended to use HFO, HFOE andHFOU pillow blocks designed for self aligning bearings with cylindrical bores. Mounting of bearings withcylindrical bores directly on the shaft results in maximum concentricity and achievement of the designlimiting speed.

In the event that the supports are operating near the limiting speed it is necessary to take intoconsideration during the selection phase derating of the maximum speed if the ratio of Fa/Fr is greaterthan >0.3.At Fa/Fr =0.6 the derating factor is 0.8. If the Fa/Fr ratio is >0.6 consult DODGE engineering.

Bearing Radial PlayIf the RPM exceeds 70% of the limiting speed of the bearing as found in the manufacturers catalogsbearings with higher internal clearance must be selected such as C3 due to higher running temperatures.At the same time if there is heat being introduced into the blocks via the shaft so that the temperaturedifference between inner ring and outer ring is greater than normal then bearings with even higherinternal clearance than C3 must be selected.

Bearings with tapered bore can be removed from the shaft easily with the help of hydraulic sleeves.However some important items must be taken under consideration.

During mounting attention must be paid to the mating surfaces between cap and base. To these surfacesa bead of silicon sealer or equivalent should be applied. It is important also that a sealant be applied tothe gaskets between the end covers and the pillow block face. The oil ring must always be mounted andmust rotate freely. Without oil ring, after a short time, it is possible that the bearings run withoutlubrication and fail.

For HFO’s pillow blocks with cylindrical bore spherical roller bearings it is advisable to mount the oil ringon the side adjacent to the end of the shaft. For HFOE’s the oil ring is always mounted on the inboardside of the pillow block. For pillow blocks supporting shafts with electromagnetic couplings it isrecommended to use a brass oil ring instead of the steel one. The vent on the oil sight gauge must bekept free and unplugged in that a bubble of air in the tube can cause an oil level error.

MaintenanceBefore start-up the pillow block must be filled with the proper volume of oil. Minimum and maximum oillevels are shown on Table 2. The maximum oil level guarantees lubrication at start-up when the oil ringcan not yet lubricate the bearing.

Before each start-up and after each long duration shutdown the oil level in the sump must be brought tothe maximum level by adding oil if necessary.

Even after having carefully cleaned the pillow block prior to mounting it is possible that some dirt willremain in the pillow block cavity, therefore it is recommended that after two or three hours of initialrunning a full oil change be carried out. Oil change frequency should be based on the oil type used andon the running conditions especially running temperature. Oil change should be done at least once ayear. Oil change must take place when the system is shutdown. If during trial runs no leaks weredetected it is sufficient to inspect oil level once a month. During running periods the oil level can be as lowas the minimum level shown on Table 2. While running it is possible to add oil up to 5 mm below themaximum level shown on Table 2 in that if more is added in addition to that already in the sump anexcess amount could result.

DODGE HFO pillow blocks incorporate on the top of the cap a blind hole (M24) plugged with a plasticplug. If necessary, via this hole, it is possible to insert a thermometer or a temperature sensor formeasuring temperature or for the control of temperature. The hole reaches down close to the bearingouter ring, so it is possible to measure temperature very close to the temperature source. Using thissystem faster response can be achieved than measuring the temperature of the oil sump. HFOE do notoffer this feature.

How to orderWhen ordering it is not enough to order an HFO or an HFOE pillow block, but must be specified all theother components such as anti-friction bearing, adapter sleeve, lockwasher and locknut and eventuallyeven the brass oil ring, e.g.:1-Pillow Block type HFO 220 AF1-Spherical roller bearing 22220C/C3 1-Shaft nut type KM201-Lockwasher MB201-Oil ring in brass

or 1-Pillow block type HFOE 626 BL1-Spherical Roller bearing 22326 CK/C31-Adapter Sleeve Assembly H 2326

Special RequirementsWhen HFO, HFOE or HFOU pillow blocks are being used to support shafts with electromagnetictransmission members, then the steel oil ring must be substituted with a brass oil ring. The part numbersfor the brass rings are listed on Table 4 below:

Allowable LoadsPillow blocks of the series HFO have been designed for loads acting thru the base or thru the cap. Ifother load conditions exist they must be checked against the strength of the block itself as well as againstthe cap bolts and the base bolts strength. Table 5 below lists the fracture loads of the pillow blocks whenthe forces are acting at 55, 90, 120, 150 and 180 degrees from the base as well as strength of the fourcap bolts when the forces are acting at 120, 150 and 180 degrees from the base. Also shown on Table 5is the maximum permissible thrust load.
