Due to the different ways of use, bearings can be divided into high-speed bearings and low-speed bearings, but although this is said, the basis of their distinction is not simply counted by how many revolutions can be rotated, and some low-speed bearings have a The rotational speed can reach nearly tens of thousands of revolutions, but although some are called high-speed bearings, their rotational speed is only a few hundred revolutions per minute. The distinction is based on the linear speed of the bearing. High speed bearings are high speed bearings. Now, the low linear speed is the low speed bearing.
Low-speed bearings generally use rolling bearings, high-speed bearings generally use sliding bearings, that is, the place responsible for rotation in the bearing is different. The low speed bearings use circular, cylindrical or even conical rotors; and high speed bearings use bearing bushes, please pay attention to: Rongji igniter.
