FEATURES

RA20013 Crossed roller bearing Belongs to Model RA Separable outer ring type,200X226X13MM

RA20013UUCC0 Crossed roller bearing used for Robot rotating parts 200x226x138mm
LYMC Precision bearing offer crossed roller bearing RA20013UUCC0 with 200x226x138mm P5 P4 P2 accuracy rotating grade. 

RA20013 crossed roller bearing structure despite the minimum possible dimension of the inner and outer rings,

its outer ring is separable while the inner ring is integrated with the main body. This model is used in locations 

where the rotation accuracy of the inner ring is required.

 

Bearing Structure and Features:

Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles 

to each other between inner and outer rings. They can take loads from any directions at the same time 

such as radial, thrust and moment loads. The rollers make line-contact with raceway surfaces, 

and, therefore, elastic deformation due to bearing loads is very small.These bearings are widely used in the rotating parts 

of industrial robots, machine tools, medical equipment, etc., which require compactness, high rigidity and high rotational accuracy.

In addition, bearings made of stainless steel or those with inner and outer rings provided with mounting holes are also available on request.
