NTN Yoke Type Track Rollers are the rolling mechanisms whose outer ring rolls on a track. For example, these track rollers are applied to eccentric roller, guide roller, rocker arm roller, cam roller and pressure roller. For that, the outer ring is designed to a wall thickness so as to be resistible to high load and shock load. Both spherical outer surface (rolling surface) and cylindrical outer surface are available for the outer ring. The spherical outer ring can withstand edge-load acting on the contact surface between the track and the track roller, while the cylindrical outer ring (Tail code: X) has track load capacity greater than the spherical outer ring.
