FAQ

1. Which precision grade of RA18013UU bearing and clearance shall I select?
Below is the rotation accuracy and clearance standards, users can select based on their actual application and requirements. Your could also contact us for professional suggestions.

2. How to lubricate RA series crossed roller bearings?
Unless otherwise stated, all BRS made RA crossed roller bearings are filled with proper amount of complex lithium grease before delivery. So users can directly put bearings into application after receiving goods. Then after 1~6 months operation, bearings should be added with proper grease through grease holes on the outer ring based on working conditions.

RA18013 cross roller bearing installation instructions

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 by using fixing plates, etc.
3. Slightly loosen the fixing bolts of bearings outer ring during mounting.
