Crossed Roller bearing 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.

CRBH Series crossed roller bearings

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.

Features of Mounting Holed Type High Rigidity Crossed Roller Bearing

• High Rigidity and Accuracy: Both inner ring and outer ring have solid one-piece construction. Can directly mount onto the equipment through prepared mounting holes. Therefore,high accuracy and high rigidity are realized and mounting error can be minimized.
• Space Saving : Housing and fixing plate are not necessary for mounting,and the room around the bearing can be minimized.
• Smooth Rotation: Special separators are incorporated between cylindrical rollers allowing smooth and high-speed rotation.

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, please contact YDPB
