What Are the Types of Ball Bearings?

Single ball bearings are an improvement on traditional oil-sealed bearings. It is lubricated with a ball between the rotor and the stator and is lubricated with lubricant. It overcomes the short life of oil-sealed bearings and the instability of operation, while the cost increase is extremely limited. Single ball bearings absorb the advantages of oil-sealed bearings and double ball bearings. Increase the service life of the bearings to 40,000 hours, and when the ball is added, the operating noise increases, but is still less than the double ball bearing.

Double ball bearings are relatively high-grade bearings. There are several tiny steel beads in the bearing around the axis, and when the fan page or axis rotates, the beads rotate. Because they are spheres, friction is small and there is no problem of oil leakage. The advantage of dual ball fan is long life, about 50000 to 100000 hours; The disadvantage of dual ball bearings is that they are expensive to manufacture and have the greatest noise at the same speed level (because the ball bearing friction points are increased by 2 times).

Centrino thrust ball bearings are also translated into corner contact ball bearings. Angle contact ball bearings can withstand both radial and axial loads. Can operate at higher speeds. The larger the contact angle, the higher the axial carrying capacity. High-precision and high-speed bearings typically take a 15-degree contact angle. Under axial force, the contact angle increases. Single-row angle contact ball bearings can only withstand axial load strain in one direction, which causes additional axial forces when carrying radial loads. And only limit the axial displacement of the axis or housing in one direction. If the two-pair installation, so that a pair of bearings relative to the outer ring, that is, wide end facing the wide end face, narrow end face narrow end face. This avoids causing additional axial forces and limits the shaft or housing to the axial play in both directions.
