Several factors of bearing type selection


Conical hole

Bearings with conical holes can be mounted directly onto the tapered journal (eg single row and double row cylindrical roller bearings in high precision construction). A given radial clearance can be adjusted when installing such bearings.

Most of the self-aligning ball bearings with tapered bores, drum roller bearings and spherical roller bearings can be mounted to the cylindrical journal via an adapter sleeve. These bearings are particularly easy to install and remove.


The stiffness of a bearing is usually the force required to cause a certain elastic deformation of the bearing. Bearings on machine tool spindles and pinion shafts require high stiffness. Due to the different contact conditions of the rolling elements and the raceways, the rigidity of the roller bearings is higher than that of the ball bearings.

In addition to being heated and dissipated, internal friction also plays a large role in determining the operating temperature of the bearing. Low-friction bearings are: deep groove ball bearings with radial loads, single row angular contact ball bearings and cylindrical roller bearings with cages.
