There are many models of precision crossed roller bearings with similar structure, how to distinguish them? I hope this article can be helpful to everyone.
Now, the precision crossed roller bearings produced by Luoyang LIKE Precision Machinery Co., Ltd can completely replace the imported brands from Japan and Germany, and the main series of our domestic precision crossed roller bearings are RB type, RE type, RU type, RA type, SX type, CRBH type, CRBT type, and XSU type.
These models belong to THK, IKO, INA company models respectively, the following we will distinguish from the model, structure, use to understand.
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.
Bearing characteristics.
1、High precision: the precision can reach P4, P2 level.
2、High rigidity: the series bearings are with preload.
3、High bearing capacity: It can bear axial load, radial load and overturning load.
4、Small volume: the bearing is small in size, which can save space for the host.
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.
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.
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.
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
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.
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.
The XSU 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.
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
