roll neck bearings 2017-11-22 18:17:27

Steel metal rolling operations usually deform the materials by compressive forces between two constantly spinning rolls. These forces act to reduce the thickness of the metal and change its grain structure. Besides, the rolls will also feed the material when they are spinning to each other.


However, the rolls cannot function in isolation. During the rolling process, rolls, stands, bearings, housings, and motors are necessary parts for the operation. Usually, bearings will transmit motion and forces. They are usually mounted on the rolls and inserted into the housings. This is why the bearings on the mill stands are called roll neck bearings. These bearings should be strong enough to face with extreme temperatures, dust, contaminants, and variable humidity. They will also work under physical stresses of continuous high speed, extreme torque and shock loads.
