Cross Tapered Roller Thrust Bearing-xr889058

1.Cross tapered roller thrust bearing:

1).Crossed tapered roller bearings is crossed cylindrical roller bearing a deformation, its rolling body for tapered roller, adjacent roller into 90 degrees crossover arrangement of the scroll, .

2).tapered roller bearings intersection in the extension to turn the characteristics of online, this

bearing is rolling body in athletic process for pure rolling, avoid relative sliding, thus limiting speed than crossed cylindrical roller bearing, but friction torque below crossed cylindrical roller bearing.

2.Applicable scope:

Widely applied in high-speed vertical lathe, high precision worktable and, vertical boring, grinding spindle etc.
