TAPER-LOCK type W weld-on hubs aredesigned for use in applications such aswelding to plate sprockets, pulleys, and agitators. They are made of steel, drilled,tapped, and taper bored for TAPER-LOCKbushings.
U.S. Tsubaki offers the most complete line of QD® and TAPER-LOCK weld-on hubs forinsertion and welding to produce “B” stylesprockets, sheaves, and other applicationswithout hub protrusion. To provide greaterstrength for this type of shaft-locking mechanism and to reduce heat distortioncaused by welding, these hubs are dimensionally
the same as our sprocket items. Special dimensional hubs are available per your spec-ifications on a made-to-order basis.All U.S. Tsubaki hubs are made from steelbar stock (not powdered or sintered metal).The QD and TAPER-LOCK weld-on hubs listed below include appropriate taperedbores and mounting holes.
Dimensions are in inches unless otherwise indicated.

You need Adjustable Idler Sprockets to:• Obtain proper chain tension when neither driving nor driven
shaft is adjustable, and to take up slack chain developedthrough normal chain wear
• Guide chain around an obstruction • Prevent whipping action in the slack span of chain transmitting
an uneven load • Bring about greater chain wrap around a small sprocket,
particularly if it is the lower sprocket in a vertical drive • Provide for reversed direction of rotation of a sprocket in
contact with the outside of the chain
Idler sprockets should not rotate at greater speeds than areallowable for drive sprockets of the same size. They should bemounted in contact with the slack span of chain. Mount them onthe outside of the chain when the arc of chain wrap on thesmaller sprocket would otherwise be less than 120°.
It is advisable that idler sprockets have at least three teeth inmesh with the chain. Inside mounted idlers usually account forquieter operation, especially if centers are short and speed ismoderately high.

Sprocket Diameters
SprocketTerminologyHub TypeHub type refers to the core of the sprocket. Each of the three standardhub types is designed for a specific need.
• Type A has no hub extension and must be mounted on aflange, hub, or other holding device.
• Type B has a hub extension on one side and is usually foundon small or medium-size sprockets.
• Type C has hub extensions on both sides and is usually foundon large-diameter sprockets.
Number of TeethThe number of teeth on a sprocket is determined by chain pitch andsize. Larger sprockets, which have more teeth, generally last longerthan smaller sprockets because wearing action is distributed over agreater area. Double-pitch sprockets, which have two teeth per chainpitch, also obtain longer wear life because only half the teeth engagewith the chain per revolution. An odd number of teeth will engagewith the chain only every other revolution, essentially doublingsprocket life. Periodically advance one tooth to obtain the same effecton double-pitch sprockets with an even tooth count.
Maximum Bore DiameterThe bore must be large enough to accommodate the shaft whilemaintaining sufficient hub wall thickness for proper strength.
Length Thru Bore (LTB)Length thru bore, or hub thickness, must accommodate a keywaylong enough to withstand shear stress from the shaft.
Pitch DiameterThe diameter of the pitch circle that passes through the center of thepin as the chain engages with the sprocket.
Outside DiameterThe diameter measured from the tip of one sprocket tooth directlyacross to the tip of the corresponding sprocket tooth.
Bottom DiameterThe diameter measured from the seating curve at the bottom of onesprocket tooth space directly across to the seating curve at the bottomof the corresponding sprocket tooth space.
Caliper DiameterFor sprockets with an odd number of teeth, measured from the seatingcurve at the bottom of one sprocket tooth space across to the seatingcurve at the bottom of the sprocket tooth space nearly opposite.

All U.S. Tsubaki sprockets are made from highquality steel. Since chain loadings are evenlydistributed over all engaged sprocket teeth,tooth breakage or distortion is not normally aproblem. It is seldom necessary to use specialhigh strength material.
Sprocket diameter and pitch determine the specific material used.
The hardening process of small diameter, smallpitch sprockets is usually a one-step procedure:heat treatment (electrical induction). Largediameter, large pitch sprockets can usually bedirectly flame hardened. These methods areused to provide a high hardness at the wearareas, plus provide the ability of the tooth toabsorb shock loads. This is accomplished byhardening only the wear area of each toothwhile maintaining a ductile tooth core which istough and resilient. The hubs and bores remainsoft to permit reworking.
The general guidelines for sprockets are:

The above maximum bores are not approved for severeservice conditions or for Cast Iron Sprockets.
For severe service conditions maximum bores should not begreater than 2⁄3 of the diameter of the hub.
Maximum bores for Cast Iron Sprockets should be about 15%less than for steel with 1⁄4” as the minimum difference.

U.S. TSUBAKI SPROCKETS
Regardless of application, all chain systems should be inspected on a regularly scheduled basis for worn, damaged or broken parts, possible interference by other system components, and proper lubrication. Normal maintenance procedures can prevent most of the conditions described below. Carefully inspect roller chain driveson the same schedule as associated equipment.
SPROCKET MISALIGNMENTWear on the sides of sprocket teeth generally indicates improperinstallation of sprockets and/or shafts. If shafts are out of parallel or not in the same plane, non-symmetrical wear will appear onsprockets or chain rollers.
After proper alignment is made, retighten set screws in sprockethubs.
CHAIN WEAR AND ELONGATIONNormal wear will cause some increase in chain length. However, if a sudden increase in elongation occurs, look for severe wear onthe tips of sprocket teeth. This may be caused by any of the following:excessive loading or shock loading, displacement and/or wear inbearings, displacement of takeups, or under-designed drive.Elongation of 3% or more may be an indication that chain and/orsprockets should be replaced.
Before replacing chain or sprockets, recalculate initial drive design.Check chain for broken parts. Check chain tension if there is toomuch accumulated slack in the drive.
BROKEN CHAIN PARTSGenerally caused by an overload drive, extreme misalignment, excessive elongation causing chain to jump sprocket teeth, heavyshock, improper drive design geometry, or foreign objects.
Recalculate initial drive design and make necessary corrections.Inspect sprockets and shafts for proper alignment or looseness.
LINK PLATE WEARWear on edges of outer sides of link plates may be caused by chaincontacting a case or fixed object.
Remove or relocate fixed object. Readjust chain properly.
EXCESSIVE NOISECan be caused by broken links and chain rollers, extreme misalignment,elongation, chain jumping sprocket teeth, loose sprockets, broken teeth,accumulation of dirt packed into the chain or sprocket teeth, interferenceby foreign objects, or contacting a fixed object.
Check for worn, broken, or missing parts. Check alignment of shaftsand/or sprockets.
EXCESSIVE VIBRATIONUnbalanced rotating parts, broken or missing rollers, too much chainslack, loose or misaligned sprockets or shafts.
Inspect chain and drive equipment. Replace or readjust as needed.
IMPROPER LUBRICATIONLight or dark brown discoloration of pin-bushing joints and connectinglink pins, or brown-red oxide color in oil may indicate chain is not dipping into the oil reservoir, or drip lubricator or spray is plugged.
Carefully clean and dry chain, immerse in oil, and reinstall. Change oilin chain case and flush case. Determine that oil supply is adequateand unimpeded.
SUGGESTED REPLACEMENT PROCEDURESChain parts should never be altered or tampered with by makeshiftrepairs and/or with parts or components which have not been authorizedby the company.
REMOVING CHAINTurn the drive until a connecting link is fully engaged with one of thesprockets so as to relieve the tension on the connecting link pin. Theconnecting link may then be removed.
CUTTING RIVETED CHAINThe two pins of a pin link must be driven out of the link plate. Strikethe pins alternately to avoid distortion of the roller link plates as wellas the plates of the adjacent links.
PERIODIC CLEANINGRemove chain from sprockets and wash in kerosene. If chain is badlygummed, soak in kerosene and rewash in fresh liquid. Drain offkerosene and soak in oil to restore lubrication. Drain off excessivelubrication by hanging chain. Carefully inspect entire chain before reinstalling. Sprockets should be washed in kerosene.
STORING CHAINWhen roller chain is taken out of operation for a prolonged period,remove the chain and cover with heavy grease. Wrap in heavy grease-resistant paper and store where the chain will not be exposed toabnormal moisture, temperature, or abrasive or corrosive conditions.Sprockets remaining on shafts should be covered with heavy grease.
When the drive is put back in service, remove the grease and thoroughlyclean sprockets and chain before reinstalling.
HEATING AND WELDINGDo not use a cutting torch on chain. If cutting by torch is indicated,chain should be replaced. Welding should not be performed on anychain or chain components.
INSERTING NEW LINKSInsert new links only on new roller chain. Pitch variance between anew link and those on an old chain, especially one which is elongateddue to wear, will cause shock when the new link engages the sprocket.
INSTALLING NEW CHAINChain and/or related parts should be visually inspected for damagewhich could have occurred during shipment prior to installation. Neverinstall on badly worn sprockets as this will permanently damage thechain. As a temporary expedient, reverse a worn sprocket on the shaftto present a new set of working tooth surfaces. Worn sprockets shouldbe replaced as soon as practical to avoid permanent damage.
WARNING!USE CARE TO PREVENT INJURYCOMPLY WITH FOLLOWING TO
AVOID SERIOUS PERSONAL INJURY:1. Guards must be provided on all chain and sprocket installations in
accordance with provisions of ANSI/ASME B15.1—2000 “SafetyStandards for Mechanical Power Transmission Apparatus”, and ANSI/ASMEB20.1— 2000 “Safety Standards for Conveyors and Related Equipment”,or other applicable safety standards. When revisions of these standardsare published, the updated edition shall apply.
2. Always lock out the power switch before installing, removing, lubricatingor servicing a chain system.
3. When connecting or disconnecting chain:a. Eye protection is required. Wear safety glasses, protective clothing,
gloves and safety shoes.b. Support the chain to prevent uncontrolled movement of chain and
parts.c. Use of pressing equipment is recommended. Tools must be in good
condition and properly used.d. Determine correct direction for pin/rivet removal or insertion.
