RB1000110 Precision cross roller bearings

With the rapid development and increasingly mature of domestic high-precision machining equipment, more and more high-precision CNC machining equipment such as CNC indexing plates, vertical machining centers, vertical machine tools, grinding machines are abandoning traditional design and using better cross roller bearings.

Cross roller bearing is also called crossed roller bearing, the rolling body generally adopts cylindrical roller or tapered roller in a single raceway cross arranged with each other, and the roller and the roller are separated by the retainer or isolation block, which has higher rotation accuracy, larger carrying capacity, smaller overall size and higher rotation speed and rigidity. It has a wide range of uses and other bearing incomparable advantages.

This cross-arranged roller structure makes a single bearing can withstand axial load, radial load and overturning moment and other loads in all directions, and the rigidity is increased by 3-4 times compared with traditional structural bearings. At the same time, the overall size of this series of bearings is minimized to the maximum, and the special ultra-thin structure is close to the limit of miniaturization size, and has high rigidity, so it is most suitable for the joint parts or rotating parts of industrial robots, rotating tables of machining centers, robot rotation parts, precision rotating tables, rotating towers, medical instruments and other applications.

Cross cylindrical roller bearing structure

The structure of cross cylindrical roller bearing is divided into outer ring and inner ring. The outer ring, the inner ring and the inner ring are three forms of the whole. The rolling body is a cylindrical roller, which is vertically arranged in the V-shaped raceway at 9O°. The rollers are separated by an isolating block. This structure allows a single bearing to withstand all aspects of the load such as axial load, radial load and overturning moment. At the same time, due to the maximum miniaturization of the overall size, and the high rigidity and rotation accuracy of the bearing and the composite bearing capacity, it is most suitable for the joint or rotating part of the industrial robot, the rotating table of the machining center, the rotating part of the manipulator, the precision rotating table, the medical machine, the measuring instrument and other applications.

Introduction to cross cylindrical roller bearing types:

CRBH (integral, ultra-thin inner and outer rings) Due to the ultra-thin design and the absence of mounting holes in the outer and inner rings, flanges and support seats are required for installation. In addition, because the outer ring and the inner ring are integral structures, the installation has no impact on the performance, so it can obtain stable rotation accuracy and torque, which is suitable for the occasions where the outer ring and the inner ring are rotated but the size is miniaturized. RB type (inner ring integral, outer ring separate) This type is the basic type of cross roller bearings. The outer ring is divided into two pieces, and the inner ring is an integral structure, which is most suitable for occasions requiring the rotation accuracy of the inner ring.

RU type (inner and outer rings with mounting holes) Because the outer and inner rings have mounting holes, there is no need to fix flanges and support seats during installation. In addition, due to the overall structure of the outer and inner rings, installation has little impact on performance, so stable rotation accuracy and torque can be obtained. Suitable for outer ring and inner ring rotation.

RA type (inner ring integral, outer ring separate, ultra-thin) This model is a compact model that reduces the inner and outer ring thickness of RB type to the limit

The structure is the same as the RB-type outer ring split structure, which is most suitable for parts requiring lightweight and compact design, such as robot and manipulator rotation parts. RAU type size is exactly the same as RA type, its inner ring and outer ring are integral structure, more convenient installation and use.

XSU type (inner and outer ring type), this series of models does not require fixed flanges and support seats because the mounting holes have been machined. In addition, due to the integrated inner and outer ring structure with a seat, installation has little impact on performance, so stable rotation accuracy and torque can be obtained for both outer and inner ring rotation.

RB type (outer ring split, inner ring rotation) This model is the basic version of the cross roller shaft ring with a split outer ring. And form an integrated inner ring with the main body. It is best used where precision of inner ring rotation is required. For example, it can be used in the rotating part of the indexation table of a tool machine.
