FAQ

1. How to lubricate NRXT crossed roller bearings?
Unless otherwise stated, all BRS made N series 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 based on working conditions.

2. I require higher precision level, can you produce?
Yes, the standard type NRXT11020DD cross roller ring P5 grade axial/radial runout of inner is below 0.006mm, but we can produce higher precision level too. Please contact us with your detailed requirements.

NRXT11020DD 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.
