U.S. PatentAll Linear Way features unique design in which large diameter steel balls contacting raceways at four points each are arranged in two rows. High level of accuracy, even in Micro Linear Way, is realized by ’s all of accumulated linear motion technology and this simple structure.

All products are made by stainless steel which is highly corrosion resistance. This is suitable for the use in clean rooms and places where rust preven-tive oil should be avoided or kept to a minimum.

The standard end plate made by resin can be replaced with stainless steel made end plate.It is suitable for vacuum and high temperature application. Applicable to size 2 and 3.

Several greases for clean room application are available. For size 3 and 6, specify a grease by supplemental code if necessary.

Load Rating and Life

Basic dynamic load rating C

The basic dynamic load rating is defined as a constant loadboth in direction and magnitude under which a group ofidentical Micro Linear Way LWL series are individuallyoperated and 90% of those in the group can travel 50×103 m

free from material damage due to rolling contact fatigue.

Basic static load rating C 0

The basic static load rating is defined as a static load thatgives a prescribed constant contact stress at the center of thecontact area between roll ing elements and racewaysreceiving the maximum load.It is the allowable limit load that permits normal rolling motion.Generally, the basic static load rating is used in combinationwith the static safety factor.

Static moment rating T0, TX, TY

The static moment rating is defined as a static moment load(See Fig.3) that gives a prescribed constant contact stress atthe center of the contact area between rolling elements andraceways receiving the maximum load.The static moment rating is used in combination with thestatic safety factor to give the limiting load for normal rollingmotion.

Quality lithium-soap base grease (MULTEMP PS No.2:KYODO YUSHI) is pre-packed in Micro Linear Way LWL.The quality of any grease will gradually deteriorate asoperating time passes. Therefore, periodic re-lubrication isnecessary. The re-lubrication interval varies depending onthe operating conditions of the rolling guides. A six monthsinterval of generally recommended and, if the machineoperation consists of reciprocating motions with many cyclesand long strokes, re-lubrication every three months isrecommended.Micro Linear Way LWL does not have oil hole thus, greasemust be directly applied on the raceways of track rail.Miniature Grease Injector is available and please consult

if necessary.After grease is replenished, running in is performed andexcess grease will be discharged from the inside of rollingguide. Discharged grease must then be removed beforestarting the operation. Low and stable friction can beobtained after ten to twenty times of manual strokes. It ispossible to reduce the amount of grease to make frictionalresistance lower. But careful attention is necessary to keepminimum amount of lubricant strictly for the product safety.Micro Linear Way LWL does not have end seals. When it isused in places except clean environment, preparing dustprotection cover is recommended to avoid intruding harmfuldust and particles from outside.

Precautions for Use

●1 Mounting surface, reference mounting surface, andgeneral mounting structureTo mount Micro Linear Way LWL, correctly fit the referencemounting surfaces B and D (D1 or D2) of the slide unit andtrack rail to the reference mounting surfaces of the table andthe bed, and then fix them tightly. (See Fig.4.3) In size 1, reference surfaces are available to both side ofslide unit. (D1 and D2)Track rail of LWL1-Y can be mounted in lateral direction.Two kinds of mounting methods can be chosen. (See Fig.4.1and 4.2)The reference mounting surfaces B and D (D1 and D2) andthe mounting surfaces A and C of Micro Linear Way LWL areaccurately finished by grinding. Stable and high accuracyliner motion can be obtained by finishing the mating mountingsurfaces of machines or equipment with high accuracy andcorrectly mounting the guide on these surfaces.Reference mounting surfaces of slide unit and track rail areshown in Table 11.

Remark: For LWL1, prepare the reference mounting surface not tointerference with slide unit.

●2 Female threads for mounting the slide unit and trackrail are through holes.If the fixing depth of the mounting bolts is too long, the boltswill interfere with the slide unit or track rail, resulting in poortraveling accuracy and short life. The fixing depth of themounting bolts should be kept within the values shown in thetable of dimensions. Also, small head (less than 1.8mm)screw for precision equipment is recommended for mountingof size 1. ●3 The mounting bolts for track rail are not appended.For sizes 2 and 3, prepare bolts with a fixing depth notexceeding H4 shown in the dimension table.●4 Corner radius and shoulder height of referencemounting surfacesIt is recommended to make a relieved fillet at the corner ofthe mating reference mounting surface as shown in Fig.4.1and Fig. 4.2.Table 12 and Table 13 show recommended shoulder heightand radius of the reference mounting surfaces.

●5 Multiple slide units mounted in close distanceWhen using multiple slide units in close distance to eachother, actual load may be greater than the calculated loaddepending on the mounting accuracy of the slide units on themounting surfaces and the reference mounting surfaces ofthe machines. It is suggested in such cases to assume agreater load than the calculated load.

●6 Operating temperatureThe maximum operating temperature is 120°C and acontinuous operation is possible at temperatures up to 100°C.When the temperature exceeds 100°C, consult .

Mount themwithout mixing with the sets of another group.●2 Assembling a slide unit and a track railWhen assembling Micro Linear Way LWL, correctly fit thegroove of the slide unit mounted on a steel ball holder to thegroove of the track rail, and then move the slide unit gentlyfrom the steel ball holder to the track rail in parallel direction.Steel balls are not retained in Micro Linear Way, so usingsteel ball holder is necessary when re-assemble the slide unitfrom the track rail.For sizes 2 or larger, a steel ball holder is appended as anaccessory. ●3 Cleaning the mounting surfacesWhen mounting Micro Linear Way LWL, first clean allmounting and reference mounting surfaces. (See Fig.7)Remove burrs and blemishes from the reference mountingsurfaces and mounting surfaces of the machine using an oil-stone, etc., and then wipe the surfaces with clean cloth.

●4 Tightening torque of mounting boltsThe standard torque values for Micro Linear Way mountingbolts are shown in Table 14. When machines or equipmentare subjected to serve vibration, shock, large fluctuating load,or moment load, the bolts should be tightened with a torque1.2 to 1.5 times higher than the standard torque valuesshown. When the mating member material is cast iron oraluminum, tightening torque should be lowered in accordancewith strength characteristics of the material.

Remark: Tightening torque for LWL1 is recommended to be 70 to 80% ofthe values in the table.

Note(1): Track rail lengths L are shown in Table 15.(2): Bolt is required suit to mounting structure.(3): Prepare track rail mounting bolts with a fixing depth less than H4. (4): The directions of basic dynamic load rating (C), basic static load rating (C0) and static moment rating (T0, TX and TY) are shown in the sketches

below. The upper values in the TX and TY column apply to one slide unit, and the lower values apply to two units in close contact.Remarks:1. Steel parts are made of stainless steel.

2. Steel balls are not retained. End seals are not attached.3. For LWLF4, LWLFC6 and LWLF6, stainless cross-recessed head screw for precision equipment is appended for fixing track rail. Please

indicate supplemental code /MN if unnecessary.

Precise ball retainer is incorporated and non-circulation structure pro-vide superior low friction even in the vertical operation.

Large diameter steel balls are arranged in two rows and in four point contact with the raceways, achieving compact design with high rigidity under any direction of load and moment.
