LR200 KSM Series Track Rollers

KSM LR200 Type Track Rollers (Made in Japan) Pre-filled with lithium soap grease for lifetime lubrication, these track rollers come in two variants: X-2RS with a straight cylindrical profile and 2RS with a rounded profile. Models with an outside diameter of 52mm or more include an inner ring lubrication hole. Use only lubricants matching the factory grease to prevent mixing. Designed for flat-surface operation, the heavy-duty outer ring compensates for load-induced deformation—standard bearings should not be substituted even if dimensions match.
