CRBH Crossed Roller Bearings

CRBH Crossed Roller Bearings（Integrated Inner/Outer Ring type), this model is a compact type of model RU with extremely thin outer and inner rings without mounting holes are provided, the model require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque. This model can be used for both inner-ring rotation and outer-ring rotation and the requirement of miniaturized dimension.

CRBH Crossed Roller Bearings Matters Need Attention:

These bearings are generally lubricated with grease. In relubrication, grease can be supplied through the clearance between the outer ring and inner ring.
For the bearings supplied without lubricant, customer is supposed to apply lubricant. Operating without grease or oil will increase the wear of the rolling contact surfaces and
cause a short bearing life.When using special grease, carefully examine the grease properties and contents such as base oil viscosity andextreme pressure additives. In this case.

1.CRBH Crossed Roller Bearings Structure

The Cross roller bearing is arranged by the rollers in a straight line. The Cross section area of the single row roller bearing and the ball bearing with a contact angle of 45 ° mounted back to back is reduced to one size. Not only the structure is compact, but also the rigidity is improved to 3 ~ 4 times of the double row angular contact ball bearing.

2. CRBH Crossed Roller Bearings Features

With intergrated inner ring and outer ring,High rigidity and high accurancy together with somooth rotation is provided by separator, can be used for both inner ring and outer ring rotation.

High precision: P5, P4, P2 precision
High rigidity: This series bearing have preload
High load：This series bearing can bear double-direction axial load, radial load and tilting moment
Small size: This series bearing can save space for machine tools

3. CRBH Crossed Roller Bearings appliance

Widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
