Each bearing type displays characteristic properties, based
on its design, which makes it more, or less, appropriate for a given application. For example, deep groove ball bearings can accommodate moderate
radial loads as well as axial loads. They have low friction and can be produced
with high precision and in quiet running variants. Therefore they are preferred
for small and medium-sized electric motors.
Spherical and toroidal roller bearings can carry very heavy
loads and are self-aligning. These properties make them popular for example for
heavy engineering applications, where there are heavy loads, shaft deflections
and misalignments.
In many cases, however, several factors have to be
considered and weighted against each other when selecting a bearing type, so
that no general rules can be given. The most important factors to be considered when selecting a standard bearing type are:-
1. Available space
2. Loads
3. Misalignment
4. Precision
5. Speed
6. Quiet running
7. Stiffness
8. Axial displacement
9. Mounting and dismounting 10.Integral seals.
