Crossed roller bearings consist of an outer ring, an inner ring, multiple rollers and spacers. The rollers are located between the inner and outer rings, and spacers are placed between the rollers to prevent them from rubbing against each other, thereby reducing the torque resistance to rotation. Shangyin crossed roller bearings have six types, including split outer ring type (CRBA), split inner ring type (CRBB), high rigidity type (CRBC), split outer ring with mounting holes (CRBD), high Rigid with mounting holes (CRBE) and custom (CRBX).
Crossed-roller bearings are bearings for high-precision applications whose dimensions conform to ISO dimension series 18 as per DIN 616. Due to the X arrangement of the cylindrical rollers, these bearings can support axial forces from both directions as well as radial forces, tilting moment loads and any combination of loads by means of a single bearing position. As a result, designs involving two bearing positions can be reduced to a single bearing position. Crossed roller bearings are very rigid, have high running accuracy and are supplied with normal clearance, low clearance or preload. The bearing outer rings are easily fixed to the adjacent construction using clamping rings.
AUB designs and manufactures a wide range of crossed roller bearings that can accommodate radial, thrust and moment loads simultaneously. The rollers of these compact bearings cross at right angles between the inner and outer rings.
The choice of cross roller bearing is dependent on the design requirements of the equipment and and the specific application.
The high rigidity crossed roller bearing adopts a solid one-piece structure with high precision.
Standard crossed roller bearings have a two-piece outer ring that is bolted together to prevent separation during shipping and installation.
Ultra-thin crossed roller bearings have a smaller outer diameter and narrower width compared to the inner diameter.
Ultra-thin crossed roller bearings have an extremely compact design, measuring 5.5 mm high and 5 mm wide.
