Roller Followers (Yoke Type Track Rollers)

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