Mounting and dismounting
Mounting
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 correct mounting technique 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.
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 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.
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.
