Axial guide supported roller bearing NUTR20

Axial guide supported roller bearing NUTR20

XSP curved roller consists of a bolt as the inner raceway of the roller group and a thick-walled outer ring. The shoulder of the bolt shaft and the end retaining ring pressed on the bolt form the guide surface of the outer ring along the two side directions. When the curved roller shaft 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 negative amount applied in this case is selected as the curve wheel column. The support roller has a thick-walled outer ring. With this outer ring, the roller can roll directly on the raceway and can withstand large loads. Support rollers include pressure rollers, eccentric rollers, and rocker rollers. The outer diameter of the roller is cylindrical or spherical. The tilt position during installation can be compensated by using the ball outer ring. XSP ribless support roller needle roller bearing STO type, the outer ring of this bearing adopts roller type, compact structure, thick outer ring wall, can withstand large impact force during rotation, and has good wear resistance. Since this kind of bearing has no ribs, the inner ring, needle roller and cage assembly, and roller-type outer ring can be installed separately. When the outer ring surface of the bearing is a cylindrical surface, the bearing code is STO···X type.
