Malossi roller cages are independent bearings, ready to be assembled and manufactured in high resistance steel with housings for the insertion and axial rotation of the rollers.
These devices are designed to allow reciprocal movement between two objects, preserving the seat of rotation and supporting the rotating elements with minimum dimensions, negligible weight and reduced friction.
They are essential components in internal combustion engines which, by definition, have many rotating moving parts.
As can be seen in the image, a roller cage is formed by a body (cage) with housings in which the rollers are placed, kept in their seat but free to rotate axially: this is precisely on the rollers that rests the external rotation surface and it is thanks to them that the rotation between the two components takes place.
Since these organs are subject to continuous accelerations and decelerations and, therefore, to significant inertial forces, it is essential that the cage combines lightness with high sturdiness and machining precision and that the rollers are perfectly cylindrical and are selected and coupled in dimensional classes with extremely low tolerances, of the order of a micron.
The cage itself must be manufactured to extremely tight tolerances, as it must hold the rollers apart and guide them correctly.
It should be added that the slots in which the rollers are placed must be perfectly parallel to each other to avoid unwanted movements of the rotating elements and the resulting collateral axial thrusts, which would cause severe overheating and considerably reduce the se
