www.lmotion.ru skf@lmotion.ru Тел. (495)-921-34-60MaintenanceDirt can drop and settle on exposedrails in particular. To maintain thefunction of seals and cover strips,such dirt must be regularly removed.For this purpose a “cleaning stroke”should be carried out over the entirelength of travel at least twice a day,and at the latest after eight hours.Carry out a cleaning stroke eachtime before switching off themachine.LubricationGrease lubricationInitial lubrication of the carriage(basic lubrication)No initial lubrication is required ifthe carriage has been greased at thefactory.The initial lubrication takes placewith three times the part quantitystated in Table 1:Observe the manufacturer’s instructions,in particular instructions concerningincompatibilities.Greases with a proportion of solidlubricant (such as graphite) shouldnot be used!Re-lubricating the carriageWhen the re-lubrication intervalaccording to Table 2 has beenreached, the carriage must be lubricatedwith the lubricant quantity asstated in Table 1. Where such environmentalinfluences as dirt, the useof coolants, vibration, shock loadsetc. are encountered, we recommendthat the re-lubrication intervalsbe shortened accordingly.Longer re-lubrication intervalsapply in the case of smaller loads.Short strokeStroke < 2 ¥ carriage length• 2 lube ports need to beprovided per carriage andlubricated in each case!Stroke < 0,5 ¥ carriage length• 2 lube ports need to beprovided per carriage andlubricated in each case!• For each lubrication cyclemove the carriage 2 ¥ thecarriage length. If this is notpossible, please consult SKF.Lubricant quantities as stated inTable 1 (re-lubrication). Apply thestated quantity for each lube port.* NLGI 00 greases reduce the relubricationintervals to 75 % of thevalues stated in Table 2.1. Grease the carriage with thefirst part quantity stated intable 1.2. Move the carriage backwardsand forwards with three doublestrokes along at least three timesthe carriage length.3. Repeat step 1 and 2 twice.4. Check whether a lubricatingfilm is visible on the rail.Ball rail guides are supplied in protectedform. With basic greasing atthe factory, both grease and oillubrication is possible.For lubrication we recommendlubricating grease to DIN 51825: –KP2K-20, consistency class NLGI 2to DIN 51818. This can be obtainedfrom SKF, see recommendation forlubricating greases.Never start to use carriages withoutbasic lubrication.Table 1Size Grease lubricationInitial lubrication by customer Part quantity (cm 3 ) Re-lubrication Part quantity (cm 3 )15 0,4 (x 3) 0,4 (x 2)20 0,7 (x 3) 0,7 (x 2)25 1,4 (x 3) 1,4 (x 2)30 2,2 (x 3) 2,2 (x 2)35 2,2 (x 3) 2,2 (x 2)45 4,7 (x 3) 4,7 (x 2)Table 2Size Grease lubricationRelubrication intervals under normal operating conditions, v ≤ 1 m/sTravel (km)under load ≤ 0,15 C ≤ 0,3 C15 5 000 1 20020 5 000 1 20025 10 000 2 40030 10 000 2 40035 10 000 2 40063
