KSM LR200 LR50 LR50 LR53 LR53 Yoke Type Track Rollers 
All LR track rollers are supplied grease filled. (The lithium soap grease). The LR...X-2RS have straight cylindrical outside diameter. The LR...2RS has a rounded (spherical) outside diameter. The units are supplied with lifetime grease lubrication. The size with an outside diameter 52mm or greater have a lubrication hole in the inner ring. To prevent mixing of greases with different characteristics, please insure to perform the lubrication of the units with lubricants that have the same characteristics as the grease used at the factory. 
If the track rollers operate on a flat surface / raceway, the outer ring deforms from load. Thus, is the reason these bearing is built with a heavy-duty outer ring. Standard bearings should not be substituted for this bearing even if dimensions match. MADE IN JAPAN
