China factory CRBF Series Crossed Roller Bearings with Best Sales

CRBF Series Crossed Roller Bearings

CRBF series crossed roller bearing has a compact inner and outer ring to provide high stiffness. Besides, bearings performance is minimally affected by the mounting procedure. And with mounting holes on the inner and outer ring end face, the CRBF series crossed roller bearing can be directly fixed to the related parts, even without the housing or fixing plate.

What are the meanings of the suffix A/AD/AT/UU?

A: Mounting holes of both inner and outer rings are counterbore holes that face the same direction.

AD: Mounting holes of both inner and outer rings are counterbore holes facing opposite directions.

AT: Mounting holes of outer rings are counterbore holes, while mounting holes of inner rings are tapped holes.

UU: Sealed both sides.

CRBF series crossed roller bearing features

1. Integrated inner ring and outer ring provide high stiffness
2. Sustain radial, axial, and moment loads at the same time
3. High rigidity & rotation accuracy, compact structure reduce the influence of installation
4. Miniaturization. Inner ring and outer ring with mounting holes, so it can be easily mounted to a device with bolts without need for housing and fixing plate, so surrounding parts of the bearing can be made compact, contributing to miniaturization and weight saving of devices.

Applications

Because the rotational torque of CRBF series crossed roller bearings is lower than that of traditional plain bearings, the difference between static and dynamic torque capacities is small. This enables lower power consumption and a reduced operating temperature rise, increasing overall machine efficiency. Basic active load ratings range from 2,910 to 84,300 N, and the CRBF series crossed roller bearings’ operating temperature ranges from -20° to +110° C. Ideal applications include industrial robots, machine tools, medical equipment, and other machinery requiring high rigidity and superior accuracy in a compact footprint.
