Equal section thin wall bearing overview

Writer: admin Time:2022-09-20 13:20 Browse:

The cylindrical rollers of the HRAU series of equal-section thin-walled crossed roller bearings are arranged in a cross on the V-shaped raceway, and the rollers are separated by spacers. Bearing loads in various aspects such as axial load, radial load and overturning moment. In addition, since the inner and outer rings are of integral structure, it can be used for the rotation of the inner ring and the rotation of the outer ring.
 
 
Due to the maximum miniaturization of the external dimensions, and the high rigidity and rotational accuracy of the bearing, as well as the composite bearing capacity, it is most suitable for the joints or rotating parts of industrial robots, direct drive motors, medical equipment, measuring instruments and other fields. 
Equal Section Thin Wall Crossed Roller Bearings



 
The cylindrical rollers of the HRAU series of equal-section thin-walled crossed roller bearings are arranged in a crisscross pattern on the top of the V-roller, and the rollers are separated by spacers. It can bear various loads such as axial load, radial load and overturning moment. In addition, since the inner and outer rings are of integral structure, it can be used for the rotation of the inner ring as well as the rotation of the outer ring.
 
Equal Section Thin Wall Ball Bearings
Deep groove ball bearings: C-type deep groove ball bearings are single row deep groove ball bearings with ultra-deep grooves (raceway groove depth = 25% of ball diameter) in the inner and outer rings.

Angular contact ball bearings: The difference between A-type angular contact ball bearings and C-type bearings is that A-type bearings have sufficient radial clearance and can form a sufficient contact angle to bear axial loads. Due to its unidirectional load capability, the bearing needs to be mounted symmetrically with other bearings in order to set and maintain the contact angle while minimizing axial movement when subjected to alternating axial loads.
 
Four-point contact ball bearing: The difference between the X-type four-point angular contact ball bearing and the A and C-type bearings is the shape of its ball groove. The deep groove depth and four-point contact structure enable the bearing to withstand radial, axial and torsional loads, similar to a pair of Type A bearings in a back-to-back combination.
