Crossed roller bearing eight series and application
 

cross roller bearings
 

Cross roller bearing is a special type bearing with inner ring division and outer ring rotation.Because of the split inner or outer ring, after loading the roller and interval retainer, it is fixed with the cross roller ring to prevent the separation from each other. Therefore, it is easy to operate when installing the cross roller ring.Cross roller bearing structure, installation, maintenance, fault diagnosis and troubleshooting services, for you free to provide a variety of products, cross roller bearing type selection.

1. CRBH series cross roller bearings
CRBH series cross cylindrical roller bearing (integral type of inner and outer ring, ultra-thin)In addition, since both the outer and inner rings are integral structures, the installation has no impact on performance, so stable rotation accuracy and torque can be obtained, which is suitable for applications where the rotation of the outer and inner rings is required to be miniaturized.

2.RA series cross roller bearings
RA series crossed cylindrical roller bearing (whole inner ring, outer ring fission, ultra-thin) RA series crossed cylindrical roller bearing, this model is to type RB inside and outside the ring thickness decreases to the limit of the compact, the structure and RB series as outer fission structure, the most suitable for the need of light weight, compact design, such as the robot manipulator and rotating parts.

3. RB series cross roller bearings
RB precision cross roller bearing is the basic type of cross roller bearing, whose structure is two and a half of the outer ring (connected by bolts or special rivets) and the integral design of the inner ring. Therefore, the inner ring has high rotation accuracy and is suitable for the application of the inner ring rotation.For example, the rotary part of the dividing table of machine tool, the direct drive motor of internal rotor, etc.

4. RE series cross roller bearings
RE series of cross cylindrical roller bearings are also the basic type of cross roller bearings with the same profile size and RB type, but the structure is the outer ring as a whole, and the inner ring is divided into two pieces. It is most suitable for the occasions where the rotation accuracy of the outer ring is required.For example, external rotor direct drive motor.

5. RU series cross roller bearings
RU series cross-cylindrical roller bearings (integral inner and outer rings, with mounting holes) this series models because of the processing of mounting holes, do not need to fix flange and support seat.In addition, the installation has little effect on performance due to the integrated internal and external ring structure of the belt seat, so stable rotation accuracy and torque can be obtained.Can be used for outer ring and inner ring rotation.

6. SX series cross roller bearings
(SX series cross roller bearing inner ring and outer ring size whole, ultra-thin) SX series cross roller bearing, in the same journal, this type than RB series has a small cross section size, the adoption of ultra-thin design, outer ring and inner ring no mounting holes, and the need to flanges brackets fixed, applicable to the inner ring spinning.

7. XSU series cross roller bearings
XSU cross roller bearings (inner and outer ring type) have been machined with mounting holes, so there is no need to fix flange and support seat.In addition, the installation has little effect on performance due to the integrated internal and external ring structure of the belt seat, so stable rotation accuracy and torque can be obtained.Can be used for outer ring and inner ring rotation.It is highly rigid and can reach levels P5, P4 and P2.

8. XU series cross roller bearings
The XU type (inner and outer ring type) has been processed for mounting holes, so there is no need to fix flange and support seat.In addition, the installation has little effect on performance due to the integrated internal and external ring structure of the belt seat, so stable rotation accuracy and torque can be obtained.Can be used for outer ring and inner ring rotation.Can be applied to: CNC machine tools, industrial robots, CNC turntable, CNC vertical, precision rotary table, testing instruments, precision equipment.
