LR50 LR600 LR6000 KSM Track Rollers

KSM LR50, LR600, LR6000 Yoke Type Track Rollers (Made in Japan)
Pre-filled with lithium soap grease for lifetime lubrication, these rollers come in two designs: X-2RS models have a straight cylindrical profile, while the 2RS models are rounded. Models with an outside diameter of 52mm or more feature an inner ring lubrication hole. To avoid mixing grease characteristics, always use a lubricant that matches the factory fill. Designed for flat-surface operation, the outer ring deforms under load, which is why a heavy-duty outer ring is used—standard bearings should not be substituted, even if the dimensions match.
