65BNR10ETYNDBBELP4 NSK spindle bearing used for machine tool main spindle center.

                                  65BNR10ETYNDBBELP4 NSK spindle bearing used for machine tool main spindle center.

It  including outer ring inner ring cage and ball parts that belongs to  high precision accuracy angular contact ball bearing.

Most spindle designs include an outer cap whose male register surface should lightly compress the bearing's outer ring. Suggested axial compression: 10-30μm.

•The male register's surface should be flat and parallel to the outer cap mounting flange surface that contacts the housing. This will ensure even clamping pressure against the bearing outer ring.

Excessive and/or uneven clamping pressure can result in bearing noise or loss of preload.

65BNR10ETYNDBBELP4 spindle bearing Method of Cleaning,

1. Use Kerosene or light oil to clean the bearings.

2. Use separate tanks for first cleaning and final cleaning. Each tank should

be equipped with a wire rack to prevent direct contact of the bearing with any contamination that may have settled at the bottom.

3. In the first cleaning tank, avoid rotating the bearings. After cleaning the outside surfaces with a soft brush, move the bearings to the final cleaning tank.

4. In the final cleaning tank, rotate the bearing by hand very gently. Make sure that the cleaning fluid in the final cleaning tank is kept clean.

5. Remove excess cleaning fluid from the bearing after cleaning. Allow the bearing to completely dry before applying grease or oil using a lint free cloth.
