Cross roller bearing specification

With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90° V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads.
Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary

units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.

Cross roller bearing RE relative series

RB type ( outer split type )

RB series model for cross- Cylindrical roller bearings of the basic model , the inner and outer dimensions are the minimum possible , its structure is the outer ring is split type , the inner ring is the one designed for applications requiring high precision rotation of the inner parts .

RE-type ( inner split type )

RE series model is shaped by the XRB generated new style design , the main dimensions and XRB same type . Its structure is split inner ring is the type , the outer ring is the one designed for applications requiring high precision rotation of the outer parts .

RU -type ( inner and outer one size )

RU series models have been carried out since the mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring .

RBC -type ( outer split type )

RBC Series models ( corresponding to the IKO's CRBC series ) whose structure is the outer ring is split type , the inner ring is integrated design , with cage full complement cylindrical roller bearings. Suitable for applications requiring high precision rotation of the inner parts .

CRBH type ( inner , outer one size )

CRBH series models , the outer ring is integrated structure for the outer ring and the inner ring rotates.

RA type ( outer split , ultra-thin )

RA Series models are the RB type , the outer ring thickness is reduced to the limit of the compact . For applications that require light weight, compact design of the site, such as robots and robotic rotating parts .

SX type ( outer split type )

SX Series Model Structure and RB series is similar to the structure of the outer ring is two divided by three snap ring connection , the inner one designed for applications that require high precision rotation of the inner place .

XRU08 type ( inside and outside the ring one size )

XSU08 series with RU series are similar, have been carried out outside the ring mounting holes of the processing, you do not need a fixed flange and the housing . Further, since the use of external integrated with the seat ring structure mounted almost no effect on performance , it is possible to obtain stable rotation and torque accuracy . Can be used to rotate the outer ring and the inner ring .
