Loads of Electrically Insulated Rolling Bearing
In order to select the best bearing for a particular application, all operational loads should be taken into account. In addition to the weight of the components, the forces created when power is transmitted, such as those listed below, should also be considered:
- the magnetic pull resulting from asymmetrical air gaps
- dynamic forces due to misalignment
- out of balance forces
- forces due to pitch errors in gears
- thrust loads
Loads can be radial, axial or a combination of the two. In cases where there are heavy loads,
Roller bearings are typically used. Ball bearings are generally used for lighter loads. Certain bearings, such as NU322 ECM/C4VA301 cylindrical roller bearings, accommodate radial loads only while other bearings, such as angular contact ball bearings, are better suited for combined loads.
