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.

CRB/CRBC series ,its structure is with separatable outer ring and intergrated inner ring. Withcage and full complement,open type and sealed type available . Separator and cage type suite to the application requires low driving energy and high speed rotation. Full complement type is suitable to low speed rotation and heavy load.

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.

Lubrication

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
