Replacement THK Crossed Roller Bearings

Cross Roller Bearings

THK Standard Crossed Roller Bearings

THK crossed roller bearings is a roller bearing with high rotational accuracy and can carry loads in all directions. It can carry loads in all directions because it has cylindrical rollers arranged in straight crosses.

 

1. RA series (Corresponding to THK’s RA series)

RA series models are compact models that reduce the thickness of the inner and outer rings of the RB type to the limit. It is suitable for parts that require light weight and compact design, such as robot and robot rotation parts.

2. RB series (Corresponding to THK’s RB series, IKO’s CRB series)

RB type crossed roller bearings (inner ring integral, outer ring split type)

The outer ring is divided into two pieces, and the inner ring is a monolithic structure type, this series is suitable for applications with high rotational accuracy of the inner ring.

3. RE Series (THK RE Series )

Main dimensions are the same as RB type. The difference with RB is that the outer ring is of integral structure and the inner ring is divided into two pieces, which is suitable for the part requiring high accuracy of outer ring rotation.

4. RU series (Corresponding to RU series of THK and CRBF series of IKO)

RU series model, inner and outer ring one piece type. Since the mounting holes are machined, there is no need for a mounting flange or support seat. In addition, the integrated inner and outer ring structure with seat is adopted, so that mounting has little effect on performance, and stable rotational accuracy and torque can be obtained. It can be used for both outer ring and inner ring rotation.

5. SX series (Corresponding to INA SX series).

The structure is similar to RB series, the outer ring is a two-part structure, connected by three spring snap rings, and the inner ring is designed in one piece, which is suitable for places requiring high accuracy of inner ring rotation.

 

6. XSU series (Corresponds to INA’s XSU series)

The XSU08 series model is similar to the RU series in that the inner and outer rings are already machined with mounting holes, eliminating the need for fixing flanges and support seats. In addition, since the integrated inner and outer ring structure with seat is adopted, mounting has almost no effect on performance, so stable rotational accuracy and torque can be obtained. It can be used for both outer ring and inner ring rotation.

 

7. CRBC series (IKO’s CRBC series)

The structure of the outer ring is split type and the inner ring is one piece design with cage full complement roller bearing. It is suitable for parts requiring high rotational accuracy of the inner ring.

8. CRBH series (IKO CRBH series)

Selling point: thin type and high precision

Advantage: Thin section design

Application: High-precision rotary applications requiring small cross-sectional dimensions

Product features: thin section size design, high precision and high rigidity bearings

9.CRBT type (THK CRBT ,IKO RAU)

CRBT crossed roller bearings (ultra-thin type) selling point: ultra-thin section design advantage: high precision use occasions: collaborative robots, special service robots, etc. product characteristics: ultra-thin section of the compact structure, high precision, high rigidity and low friction
