Product Description

 

  Precision Cross Roller Bearing, the inner structure of which adopts the vertical and cross arrangement of cylindrical rollers with 90°, can bear radial load, double-direction thrust loads and overturning moment at the same time. Combined with its high rigidity, it can be applied to the joints and rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical equipments, measuring instruments, IC manufacturing machines, etc.

  Precision Cross Roller Bearing has three structure types, including bearing   with cage, with separator, and with full complement. Cage and separator types are suitable to low friction moment and high-speed rotation, while full complement is suitable to low-speed rotation and heavy load.

  Precision Cross Roller Bearing has the following seven structure series:

Precision Cross Roller Bearing has the following seven structure series:

 RB Series

 RE Series

 RU Series

 RA Series

 RA-C Series

 CRB Series

Technological Process

All the forging will be inspected to ensure there is no defect in the material.

Rough Turning with 2-3mm allowance according to the drawing, at the same time every parts will be inspected to ensure the dimension is satisfy with the drawing requirements.

Finish lathing with 2-5mm allowance according to the drawing, all the parts will be inspected to ensure the dimension is satisfy with the drawing requirements

The tolerance of center diameter shall be 0.05mm, and the holes shall meet the drawing requirements . The holes of each part shall be tested to ensure that they meet the requirements of the drawing.

Quenching will be done on the raceway of the bearing to improve the hardness, abrasive resistance and fatigue strength of the bearing. The hardness will be satisfy with customer's requirements after quenching. after quenching,the outer diameter,ovality will be inspected.

Grinding include rough grinding,regrinding and finished grinding. After each grinding processing, the bearing will be tempered to prevent the deformation and cracking, and release the internal stress to make the material stable,and ensure the processing accuracy, then the next grinding will be done, Top and bottom surface,inner and outer diameter, raceway will be grinded to make the dimension and the precision meet the drawing requirements, every parts will be inspected to ensure all the bearing meet the drawing requirements

100% inspection shall be carried out on each part to ensure the inner diameter, outer diameter, surface and raceway of the bearing ring can satisfy the drawing requirements, and ready for assembly.

 

Final inspection will be done after assembly to ensure all the bearing are 100% qualified.

Typing according to the customer's requirements, or typing our company's brand, and the bearing will be packaged by Plastic film+plywood case, or according to the customer's requirements.
