(Separable Outer Ring, Type for Inner Ring Rotation)

CRB series(Separable Inner Ring,Type for Outer Ring Rotation)

Its structure is that the inner ring is separable while the outer ring is integrated with the main body.without cage ,but full complement.this model is used in locations where the rotation accuracy of the outer ring is required.

CRBC series(Separable Inner Ring,Type for Outer Ring Rotation)

Its structure is that the inner ring is separable while the outer ring is integrated with the main body.with cage and full complement.this model is used in locations where the rotation accuracy of the outer ring is required.

Structure features of CRB15030/CRBC15030 crossed roller bearing:

With the Cross Roller bearing, 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 Crossed Roller bearing achieves high rigidity and the precision can reach up to P4.P2,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.

Rotation accuracy:

The spacer retainer fitting among CRB/CRBC series crossed roller bearing cross arrayed rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers, the Cross- Roller Ring does not cause displacement or locking of rollers and provides a stable rotation torque. Since the outer rings are designed to be separable, the bearing clearance can be adjusted. In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.

 

 

Example of installation for crossed roller bearings:

     Nowadays, as a professional percision bearing manufacture, we are proud of continual innovation, flexible production, speedy delivery, rapid after-sales service(2 years) and quick response.

       Luoyang BoYing Bearing Co., Ltd,(BYC) is a professional manufacturer of high precision bearings, which has combine researching and developing,producing and marketing together. Taking the advantage of the strong industrial basis of Luoyang, under the guidance of the pioneer in bearing industry. we grew up rapidly. After years of researching and producing practice,we have developed a very integrated system ,Now,we have solid technical strength,excellent processing facilities ,perfected production & test condition,and  also completed  quality control.

     The main products of our company are crossed roller bearings, YRT rotary table bearings, crossed tapered roller bearings. The leading products include crossed roller bearing RB, RE, RU,RA,CRBC, CRBH, XSU, SX series, rotary table bearings YRT, YRTS,YRTM,ZKLDF series, crossed tapered roller bearing JXR, XR series, almost whole range of precision bearings. The accuracy grades are P5, P4, P2, and the size of inner ring are ranging from Φ50mm --- Φ1300mm. Our products are optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines,mainly to replace the imported bearings. Also, we can design,choose and manufacture  non-standard,large size precision bearings as customer requested.

Now we adhere our management philosophy "Focus on details, Enhance self-ability",“Providing best products,and Satisfied after-sale service” We are looking forward to cooperate with customers all over the word ,contributing to the development and technology of  your enterprise.
