1, surface cleaning: The cleaning must be combined with the nature and conditions of the NSK bearing surface. Commonly used method of solvent cleaning method, cleaning mechanical cleaning and chemical trea tment method.abec bearings
2, the surface is dry cleaning the available filter clean dry compressed air. Or using a drier and dried to a temperature of 120 ~ 170 ℃, and finally with dry with a clean gauze.
DB and DF combination, can withstand two-way axial load. DB combinations farther than the distance of DF combined effect, therefore, widely used to withstand the torque load.
DT mix can only afford a one-way axial load, but the two sets of NSK Bearings equal sharing of the axial load, therefore, be used for unidirectional larger load.
The pretension level of the combined bearing in the DB and DF combined bearing, through the pre-loaded and adjusted, preferably, we can try to radial and axial displacement of the inner and outer rings is reduced to within the desired range.slewing bearing suppliers
