Around 16% of all premature bearing failures are a result of poor fitting or using incorrect mounting techniques. Individual applications may require mechanical, heat or hydraulic mounting methods for correct and efficient bearing mounting. Selecting the mounting technique appropriate for your application will help you extend your bearing’s service life and reduce costs resulting from premature bearing failure as well as potential damage to the application.
Proper mounting allows the load to be transmitted to the ring experiencing the interference fit. Mounting forces are not transmitted via the rolling elements, helping to prevent damage to the raceways. To fix a radial bearing to a shaft, generally bring the bearing into close contact with the shaft shoulders and spacer and fix it in position by tightening the shaft nut. The ends of the shaft shoulders and the spacer must be perpendicular, bearing rotation accuracy and roller contact performance will be adversely affected, resulting in heat generation and premature fatigue. The same care must be taken to ensure the proper contact between the housing shoulders and the lateral face of the outer rings.
Adequate tools and mounting methods must be provided to properly fit the inner and outer races on shafts or in housings to avoid damage. Direct shock on the races must be avoided
