What are the structural characteristics of self-aligning ball bearings?

Aligning ball bearings have two structures: cylindrical hole and tapered hole. The cage is made of steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical and has self-aligning properties, which can compensate for errors caused by non-concentricity and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees. The self-aligning ball bearing with dust cover and sealing ring has been filled with an appropriate amount of grease during assembly. It should not be heated or cleaned before installation. No further lubrication is required during use. It can adapt to the operating temperature of - 30 ℃ to + 120 ℃. between. Main uses of self-aligning ball bearings: Suitable for precision instruments, low-noise motors, automobiles, motorcycles and general machinery, etc. They are the most widely used type of bearings in the machinery industry.
