What is CRBH series crossed roller bearings?

The structure of crossed roller bearings


The crossed roller bearings has 3 kinds of structure: Outer ring division type with inner ring rotating, inner ring division type with outer ring rotating, inner ring rotation / outer ring rotation. The rolling element is cylindrical roller which vertically aligned in a V-raceway with spacer separated from each other . This structure makes individual bearing can carry axial load, radial load and overturning moment in all directions. Meanwhile, the dimensions of these bearings are maximum miniaturized. Special ultra-thin structure size is close to the limits of miniaturization also with high rigidity. It is well applied on the joints or rotating parts of industrial robots, the turntable of the machining center, robot rotation parts, precision rotary table, medical equipment, measuring instrument and other applications.

CRBH series crossed roller bearing(Integrated Inner/outer ring type, ultrathin), the ultra-thin design without mounting holes on the outer ring and the inner ring, so it requires flange and supporting pedestal when installation. In addition, because the outer ring and inner ring are integral structure, installation has no impact on performance. ensuring stable rotation accuracy and torque. This series can be used for both inner-ring rotation and outer-ring rotation and the requirement of miniaturized dimension.-www.honbyrt.com
