Type of bearing

- Oct 23, 2019-

bearing1

Low cost, high limit speed, able to bear both axial and radial forces.The contact angles of angular contact ball bearing are 15°, 25°, 40° and 60°. With the increase of contact Angle, the axial stiffness of the bearing increases, but the radial stiffness decreases. Large contact Angle is not conducive to high-speed rotation.Therefore, machine tool spindle bearing with 15° and 25°.

bearing2

High degree of rotation, high accuracy;No friction;No wear;No lube oil required;Excellent speed control performance;No noise;But the load capacity is low.

bearing3

High speed, low mechanical wear, low energy consumption, low noise, long life, no lubrication, no oil pollution, especially suitable for high-speed, vacuum, ultra-clean and other special environment, but the cost is expensive, and the technology is not very mature.

bearing4

High rotation accuracy, small friction, high speed, large load, but large pollution to the environment.
