RA cross roller bearing is outer Ring separable type and inner ring rotation design . RA type cross roller bearing is a compact cross roller bearing with the inner and outer ring thickness reduced to the limit. RA series bearings are thin-walled cross roller bearings with reduced inner outer ring thickness. The thin size design is conducive to the lightweight design of related structures. The integral structure of the inner ring is suitable for occasions with high inner ring rotation accuracy, and the stable rotation accuracy reaches micron level; it is suitable for applications requiring high precision and high rigidity such as precision testing instruments, robot joints, direct drive torque motors, and high-precision turntables.

RB type crossed roller bearing with seperate outer ring and inner ring rotation struture . The sizes of the inner and outer rings are as small as possible. The accuracy grades of RB cross roller bearings are P5, P4 and P2. It is suitable for occasions that require high inner ring rotation accuracy. The rollers of RB cross roller bearings are arranged perpendicular to each other at 90° and separated by isolation blocks, spacers and other rollers to avoid roller tilting and mutual friction. RB type fork roller bearing is a split outer ring and an integrated inner ring structure, so the gap of its outer ring can be adjusted at any time, which helps to improve the rotation accuracy of the bearing.

RE Crossed Roller Bearings is a roller bearing with split inner ring and integrated outer ring. It's a bearing with outer ring rotating structure. The main dimensions of RE cross roller bearing are the same as those of RB type cross roller bearing. It is suitable for parts requiring outer ring rotation accuracy. RE type fork roller bearing has high rigidity and high running accuracy of guide roller by optimizing preload. It is suitable for parts requiring high outer ring rotation accuracy. The thin-walled size miniaturization design is conducive to the lightweight design of related structures. The overall structure of the outer ring is more suitable for occasions with high outer ring rotation accuracy, and the stable rotation accuracy reaches μm level.

RU cross roller bearings are integrated with inner and outer rings. Both the outer and inner rings have mounting holes. No fixed flanges or support seats are required for installation. Installation has almost no effect on performance, so stable rotation accuracy and torque can be obtained. RU type cross roller bearings are suitable for occasions where the outer and inner rings rotate. Therefore, they are suitable for applications such as the joints or rotating parts of industrial robots, the rotary table of machining centers, the rotating part of manipulators, precision rotary tables, medical machines, measuring instruments, etc.

RAU micro cross roller ring Bearings, RAU type is a compact ring type that reduces the thickness of the inner and outer rings of RB type to the limit. It is particularly suitable for parts that require light weight and compact design, such as the rotating parts of the robot, and can be used in places where the inner and outer rings rotate. The RAU series can achieve lightweight and miniaturization of the device due to its extremely small cross-sectional area. The other two variants are RA type and RA-C type. The three types have the same external dimensions. The difference is that: RA type has an integral inner ring and a split outer ring, which is suitable for parts that require light weight and compact design, and has a high cost performance; RA-C type has a notched structure on the outer ring, and the outer ring also has high rigidity, so it can also be used for outer ring rotation. RAU also has an ultra-thin type with a width of 5mm and an RA type compatible type. The product lineup of the ultra-thin series starts from the ultra-small inner diameter of 10mm.

CRBH high rigidity crossed cylindrical roller bearings adopt an ultra-thin design and have no mounting holes on the outer and inner rings, so flanges and support seats are required for installation. In addition, since the outer and inner rings are integral structures, installation has no effect on performance, so stable rotation accuracy and torque can be obtained, which is suitable for occasions where the outer and inner rings rotate but miniaturization is required. The inner and outer rings of CRBH high rigidity crossed cylindrical roller bearings are both integral structures, and the dimensions are exactly the same as those of RB series and RE series crossed roller bearings, but the outer ring is equipped with a roller plate hole structure, so both the inner and outer rings can obtain strong transmission accuracy, and both the inner and outer rings can be used in rotation. The CRBH series can replace RB series crossed roller bearings and RE series crossed roller bearings.
