CRBF Series Crossed Roller Bearings

CRBF series crossed roller bearing and high rigidity crossed roller bearing with mounting holes is a compact, high rigidity, and high accuracy bearing that can simultaneously receive complex loads in any direction. This can be easily installed on the device with the mounting holes of the inner and outer rings. It is minor subject to peripheral structures such as housing pressure plate and realizes high rigidity and high accuracy operation. There are two CRBF series crossed roller bearing types: open type and sealed type.

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 (Mounting Holed; High Rigidity):

1: Mounting holes are prepared on the outer and inner rings, providing easy mounting with high rigidity and high accuracy. A single structure is adopted to reduce mounting errors for inner and outer rings. Further, mounting holes are available for direct fixing on the mating mounting surface. So high rigidity and accuracy guide can be easily realized, being minor subject to the housing structure and accuracy.
2: Contributing to miniaturization
It can be easily mounted to a device with bolts without needing housing and a fixing plate, so surrounding parts of the bearing can be compact. Further, it reduces the number of parts and assembly processes, which contributes to miniaturization and weight saving of devices.

Applications

Joint units of robots, precision rotary tables, open rotating platforms, radar, precision measuring instruments, etc.
