The usual methods for adjusting the radial clearance of NSK bearings are as follows:
1. For the backlash of the cylindrical and elliptical bearing bushes, it can be adjusted by hand grinding or scraping in the bearing.
2. For the top clearance of cylindrical and elliptical bearing bushes, it can be adjusted by manual grinding or when the condition is allowed to be padded in the bearing.
3. For multi-oil wedge fixed bearing bushes, in principle, it is not allowed to repair and adjust the bearing bush clearance. When the clearance is not suitable, the new tile should be replaced.
4. For multi-oil wedge tilting bearing bushes, it is not allowed to repair the tile. If the gap is not suitable, the tile should be replaced. For the tile with adjustable thickness, the amount of the tile can be adjusted by adding a stainless steel pad under the adjustment block behind the tile or by thinning the thickness of the adjustment block. Note that for multi-oil wedge tilting bushings, the thickness error between the same set of tiles should be less than 0.01mm.
