Cylindrical roller bearings can bear high speeds and they also have a significant radial load capacity, low friction and high stiffness. They mainly differ in the number of crowns of rollers, the edges of the inner and outer rings and for the different application needs.
It is above all the mandrels of machine tools that require their application, in which the bearing arrangements must support rather heavy radial loads, without ceasing to operate at high speed and, at the same time, ensure high rigidity.
Generally, we can say that they are used in applications that favour rotation speed and are made of different materials for particularly heavy operating conditions or in work environments in contact with polluting or aggressive agents.
They can be divided into:
