Crossed roller bearing description
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.

Seals Structure

This kind of bearings include open type and seals type.

Open type is suitable to the low energy application due to no sealing friction.
Sealed type incorporates seals made of special synthetic rubber that have excellent sealing performance against dust and dirt penetration, also prevent grease leakage.

CRBF series crossed roller bearings
Crossed Cylindrical roller with separator, Both inner ring and outer ring have solid one-piece construction, with mounting holes,high rigidity,high accurancy.

Accurancy

These bearings we can supply different precision level include P5,P4 and P2.contact us for what precision do you need.

Features

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

2. Can support axial,radail and moment loads at the same time.

3. High rigidity and rotarion accuracy,compact structure reduce the influence by installation.

4. Space Saving :  Inner ring and outer ring with mounting holes, so it can be easily mounted to a device with bolts ,Housing and fixing plate are not necessary for mounting,so surrounding parts of the bearing can be made compact, which contributes to miniaturization and weight saving of devices.

Mounting

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

Note:If you have special design ,need custom made ,pls feel free to contact YDPB ,Our engineer team can help you solve your questions.
