Yoke Type Track Roller Bearings NATR10
XSP-track roller bearings consist of a bolt as the inner raceway of the roller set and a thick-walled outer ring. The shoulder of the bolt shaft and the end ring pressed on the bolt constitute the guide surface of the outer ring along the two side directions. When the curved roller bearing moves on the flat raceway or cam plate, the internal stress of the roller increases due to the elastic deformation of the outer ring. Therefore, the amount of load applied in this case is to use curved roller needle roller bearings.
The track roller bearings have a thick-walled outer ring. With this outer ring, the roller can roll directly on the raceway and can bear a large load. The supporting rollers include pressure rollers, eccentric rollers, and rocker rollers. The outer diameter of the rollers is cylindrical or spherical. The outer ring of the ball can compensate the oblique position during installation.
