However, thequality of any grease will gradually deteriorate as operatingtime passes. Therefore, periodic re-lubrication isnecessary. The re-lubrication interval varies depending onthe operating conditions of the rolling guides. A six monthinterval is generally recommended and, if the machineoperation consists of reciprocating motions with manycycles and long strokes, re-lubrication every three monthsis recommended. Re-lubrication is performed from agrease nipple provided at the slide unit.Re-lubrication interval can be extended by using thespecial specification Capillary Platesupplemental code“/Q”. Also, re-lubrication and other maintenance workscan be reduced.Linear Roller Way Super X is dust-protected with specialrubber seals. But, if large amounts of fine contaminantsare present, or if large particles of foreign matter such asdust or chips may fall on the track rail, it is recommendedto provide protective covers such as bellows or telescopicshields for the entire linear motion mechanism.Bellows to match the dimensions of Linear Roller WaySuper X are optionally available. They are easy to mountand highly effective for dust protection.

Stable and high accuracylinear motion can be obtained by finishing the matingmounting surfaces of machines or equipment with highaccuracy and correctly mounting the guide on thesesurfaces.The slide unit reference mounting surface is always theside surface opposite to the mark. The track railreference mounting surface is identified by locating themark on the top surface of the track rail. The trackrail reference mounting surface is the side surface abovethe markin the direction of the arrow.See Fig.5.CDOperation with vibration and/or shocks4 6High operating performanceNormal operationLoad factorDue to vibration and/or shocks during machine operation,the actual load on each rolling guide becomes greater inmany cases than the theoretically calculated load. Theapplied load is generally calculated by multiplying thetheoretically calculated load by the load factor indicated inTable 11.Table 11 Load factorOperating conditions3 52.53fWLRX 30LRX 35LRX 45LRX 55LRX 65LRX 85LRXG 100BM6Equivalent to A-M6FApprox. 67.5Width across flats8M60.75JIS AM6FJIS APT18JIS APT1412.56.5 13ABFig. 4 Reference mounting surfaces andgeneral mounting structureTrack railSlide unitReference mountingsurfaceDBSmooth operation free from vibration and/or shocksNormal operation1 1.21.21.5RemarkThe above table shows representative model numbers but isapplicable to all models of the same size.Operation with vibration and/or shocks1.53markmarkFig. 5 Reference mounting surfaces231N0.102kgf0.2248lbs.1mm0.03937inch24
