Mounting is one of the critical stages of the bearing’s lifecycle
If the bearing is not mounted properly using the correct method and tools, the bearing’s service lifetime will be reduced. Individual applications may require mechanical, heat or hydraulic mounting methods for correct and efficient bearing mounting.
Mounting bearings in a cold condition
Small and medium size bearings are generally cold mounted. Traditionally, the bearing is mounted using a hammer and a length of old pipe. This practice can cause forces to be transmitted through the rolling elements, resulting in damage to the raceways. SKF’s fitting tool
helps prevent bearing damage by applying the forces to the bearing ring with the interference fit.
Mounting bearings using heat
Oil baths are often used for heating bearings prior to mounting. However, this method can contaminate the bearing, resulting in premature bearing failure. Today, induction heating is the most common technique for heating bearings since it allows a high degree of controllability, efficiency and safety. SKF has set the standards for the development of induction heaters for bearing applications. SKF bearing induction heaters are equipped with many features, which help prevent bearing damage during heating.
Mounting bearings using hydraulic techniques
SKF has pioneered the use of hydraulic techniques, such as the SKF Oil Injection Method and the SKF Drive-up Method, for mounting bearings. These techniques have helped to simplify bearing arrangements and facilitate correct and easy mounting. SKF has also developed a
comprehensive range of tools and equipment to put these hydraulic techniques into effect.
