Mechanical mounting and dismounting of rolling bearings
Mechanical tools are designed for the mounting and dismounting of bearings. The mounting forces are transmitted by the geometrical locking effect.

Cylindrical bearing seats
Smaller bearings can be driven cold onto the shaft or into the housing for normal tight fits. To prevent bearing damage, the fitting forces must always be applied to the tightly fitted ring.

Tapered bearing seats
The inner ring of a bearing with tapered bore is always mounted with a tight fit. The bearing can be either seated directly on a tapered shaft or fixed to a cylindrical shaft using an adapter or extraction sleeve. When the inner ring is pushed on, it is expanded and the radial internal clearance is reduced. The reduction in radial internal clearance is therefore valid as a measure of the seating of the inner ring. To prevent bearing damage, the inner ring must not be pushed on too far.
