RU297X crossed roller bearing specifications:

RU297X crossed roller bearing features:

1. Integrated inner ring and outer ring, provide high stiffness
2. Sustain radial, axial and moment loads at the same time
3. High rigidity & rotation accuracy, compact structure reduce the influence by installation
4. Miniaturization. Inner ring and outer ring with mounting holes, so it can be easily mounted to a device with bolts without need for housing and fixing plate, so surrounding parts of the bearing can be made compact, which contributes to miniaturization and weight saving of devices.

Cautions: For crossed roller bearings with split outer ring, when the rigidity of the mounting parts is not sufficient, stress concentration will occur at the contact area between the rollers and raceways, and the bearing performance will be deteriorated significantly.

Therefore, it is necessary to carefully examine the rigidity of housing and the strength of fixing bolts when a large moment will be applied.

1.Before installation, please clean bearing bracket, shaft, or other components, make sure there is no burrs or rough edge.
2.Fix the inner and outer rings in the axial direction directly to the mounting surface by fixing bolts
3. If large number of radial load and/or moment is applied, it is recommended to prepare flange part as Fig.4.
