Budget LFR5204-162Z Yoke Type Track Roller with U Groove 20x52x20.6mm

Metal Shielded U Groove Track Roller Bearings: These U groove profile double row ball bearings are manufactured with metal shields inserted into the outer raceway to help prevent ingress of foreign matter into the bearing and serve to retain the pre-filled grease in the bearing. The U profile ground into the outer raceway is designed to allow the bearing to run along rails or other guides. The shields can be removed for applications that only require 1 shield.
Benefits: Acts as a guide roller, metal shielded.
