Introduce  of Self aligning ball bearing:

The self-aligning ball bearing has two structures: cylindrical hole and conical hole, and the material of the cage includes steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical in shape and has automatic centering, which can compensate for the errors caused by different centricity and shaft deflection in aligning ball bearings. However, the relative inclination of the inner and outer rings should not exceed 3 degrees.

There are two types of inner holes in self-aligning ball bearings: cylindrical and conical. The taper of the conical inner hole is 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing.

Structure of Self aligning ball bearing:

It mainly bears radial loads and can also withstand small axial loads. The axial displacement of the shaft (shell) is limited within the clearance limit, with automatic centering performance, allowing normal operation under conditions of relatively small internal and external inclination. It is suitable for components where the support seat hole cannot strictly guarantee coaxiality.

The self-aligning ball bearing with dust cover and sealing ring has been filled with an appropriate amount of lubricating grease during assembly. It should not be heated or cleaned before installation, and does not need to be lubricated during use. It is suitable for operating temperatures between -30 ºC and+120 ºC.


Classification of Self aligning ball bearing:
  
series:
Micro series: 10x, 12x, 13x
Universal series: 12xx, 13xx, 22xx, 23xx
application:
Precision instruments, low noise motors, automobiles, motorcycles, metallurgy,
rolling mills, mines, petroleum, papermaking, cement, sugar squeezing and other industries.


 

load direction:

1) Radial bearing - mainly used for bearing radial loads, with a nominal contact angle ranging from 0 to 45.
According to different nominal contact angles, it can be further divided into:
Radial contact bearings - radial bearings with a nominal contact angle of 0:
Radial angular contact bearings - radial bearings with a nominal contact angle greater than 0 to 45.

2) Thrust bearing - mainly used for bearing axial loads, with a nominal contact angle greater than 45 to 90.
According to different nominal contact angles, it can be further divided into:
Axial contact bearing - thrust bearing with a nominal contact angle of 90:
Thrust angular contact bearings - thrust bearings with a nominal contact angle greater than 45 but less than 90.

Product:

1. Accommodate static and dynamic misalignment
    The bearings are self-aligning like spherical roller bearings or CARB bearings.
 2. Excellent high-speed performance
    Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
3. Minimum maintenance
    Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
4. Low friction
    Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
5. Excellent light load performance
    Self-aligning ball bearings have low minimum load requirements.
6. Low noise
    Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.
