CRBH208A cross roller bearing detail specifications:

CRBH208A bearing features:

1. Integrated inner ring and outer ring, provide high stiffness.

2. Sustain radial, axial and moment loads at the same time.

3. High rigidity & rotation accuracy, compact structure reduce the influence by installation.

4. Thin-section, space saving and reduce the overall weight of the device.

Oil groove and Oil hole on the outer ring

There are one oil groove and two lubircation holes on the outer ring diameter surface of CRBH series cross roller rings. All BRS bearings are pre-lubricated before delivery, if users have special requirements on lubrication system please notice us in advance.

Bearing tracking code

BRS conduct full-inspection on all bearing products, the QC process of high precision bearings is especially stict. Each piece of bearing will be marked with a tracking code unless customer has other request. This tracking system will help us find the problem and solve the dispute in the shortest time once there is any question.

CRBH208A(CRBH208AUU) bearing installation instructions

Cautions: For crossed roller bearings, when the rigidity of the mounting parts is not sufficient, stress concentration will occur at the contact area between the rollers and raceways, and the bearing performance will be deteriorated significantly.

Therefore, it is necessary to carefully examine the rigidity of housing and the strength of fixing bolts when a large moment will be applied.

1. Before installation, please clean bearing bracket, shaft, or other components, make sure there is no burrs or rough edge.
2. Fix the inner and outer rings in the axial direction by using fixing plates, etc.
