CRBS Crossed Roller Bearings, They are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings .The rollers make line-contact with raceway surfaces and therefore,elastic deformation due to bearing loads is very small. They can take loads from any directions at the same time such as radial,thrust and moment loads. It is possible to make your design compact comparing to the usage of taper roller bearing and combination of two ball bearings. These bearings are widely used in the rotating parts of industrial robots,machine tools ,medeical equipments,etc., which require compactness,high rigidity and high rotational accuracy.
CRBS 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.CRBS 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.CRBS 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.
3. CRBS Crossed Roller Bearings pplications
Widely used on high precision rotary table, robot joints, rotating units, sophisticated medical equipments, and measurement instruments.
