FR and LR series medium-duty track rollers are double-row ball bearings with V profiled or plain outer rings. The rollers can be supplied with normal or pre-loaded bearing clearances with concentric or eccentric centers. The roller guides have a very low coefficient of friction. AISI420 (X46Cr13 DIN1.4034) stainless steel is available on special request.
