Each type of bearing displays characteristics features which make it suitable for a certain application. Therefore, many bearings types and constructive versions have been developed so that they can satisfy various demands for rolling bearings. No general rule can be given, taking into account the great number of factors to be considered when selecting a bearing type.
Roller bearings are manufactured in varied range, both of standard design and various constructive versions.
They take double direction radial and axial loads and also allow good operation at high speeds.
For these reasons, they can be widely used. Therefore, roller bearings are manufactured in many constructive versions.
