XSU Crossed roller bearing, sealed on both sides, greased,preloaded, centred on the inside and outside diameter,

bearing rings can be screw mounted directly on the adjacent construction.

Crossed roller bearings XSU
Inner and outer ring suitable for flange mounting Crossed roller bearings XSU are screw mounted directly to the adjacent construction through both bearing rings .The adjacent construction must be flat and uniformly rigid,while the connection between the bearing adjacent components must be by force locking. For the upper and lower adjacent construction, a cylindrical pot with a flange ring has proved effective .The wall thickness of the pot should be approximately one third of the flange thickness s and the pot height HT should be at least five times the flange thickness s . For a more uniform rigidity of the bearing arrangement, thicker walls of the pot and flange ring are more favourable than thin walls with ribs.
In order to achieve the most linear force flow possible, arrange the pot precisely above or below the row of rolling elements!

Features Of Cross Roller Bearing

1.with excellent rotational accuracy

2. Installing simplifies operation

3. Bear large axial and radial loads

4.Significant savings in installation space

5. High speed capability

6. Shaft length and reduce processing costs, the geometry of thermal expansion is limited to hanges .

7. Nylon spacer, low inertia, low starting torque, easy to control angle indexing

8. Optimization of preload, rigidity, high precision guide rollers running

9. Carburizing steel provides excellent impact resistance and surface abrasion resistance

10. Simple but adequate lubrication

Series Model No.
