Hydraulic Press
Hydraulic press in the maintenance workshop are usually used to remove defect/damaged bearings from shaft. It is faster and easier to use compared to a bearing puller.
Why Bearing Pullers Are Not Usually Used
The bearing puller pulls out bearing using the same principle as a bolt. It is slow and tedious because everything is done manually by hand. A spanner is used to turn the hexagon head that will pull the cross arm.
A Bearing Puller
Induction Heater
An induction heater is used to heat up bearing so that the inner race diameter expands. This is done before installing a bearing onto a shaft. This will make the bearing slide through the shaft easier.
As its name implies, the heater used principle of induction to create heat. Normally the bearing will be heated up to 110 degree celsius.
