Precision bearings | Choosing the right bearing
A bearing is a mechanical component whose function is to guide a rotating assembly. The bearing therefore allows the rotation of one element relative to another. Bearings are therefore high-precision parts that allow equipment to move at different speed levels by efficiently transporting notable loads. They must offer high precision and durability, as well as the possibility of working at high speeds with minimal noise and vibration. This type of device is...
