RB2901401800 Crossed roller bearings

RB2901401800

The single row crossed roller bearing is composed of two seat rings, which design in compact structure and light weight; this single row crossed roller type slewing bearing has the steel roller for the rolling element, not for the steel ball. As the rollers are 1:1cross arranged, it is suitable for high precision mounting and capable to bear axial force, resultant moment and considerable large radial force. The axial and radial clearance is smaller than single row ball slewing bearing. The rotating is not so flexible as the one row ball bearings, usually it use for some higher precision applications.

Our single row crossed roller slewing bearing ring's axial and radial clearance’s precision is high.

Single row crossed roller ring bearings are mainly made of 50 Mn, 42CrMo and C45.

The single row crossed roller bearing has been widely used in many applications:

1. Military product

2. Automation machinery, Robots

3. Medical equipment

4. Radar equipment

5. Tank

6. Grinding machine and drilling machine.

Cross cylindrical roller slewing bearings main structural characteristics: 1:1 cross arrangement of cylindrical rollers.The bearing with this structure features high stability, high precision, and high impact resistance. For example, the cannon's rotary base uses this kind of bearing.

Slewing bearins are large size bearings which can carry higher axial, radial laods and overturning moments at the same time, Slewing bearing generally have mounting holes, internal or external gears, lubricant holes and sealign equipment.

Slewing bearings are widely used in cranes, excavation machines, construction machinery, port cargo handling machinery, large turnplates of high precision radars and missile launchers, etc.
