What Is Self-Aligning Ball Bearing ?

Self-aligning ball bearings are self-aligning through the inner ring, ball and cage tilting to correct misalignment between shaft and housing center, shaft deflection, etc.

Self-aligning ball bearings have two rows of balls(self aligning ball bearing double row), a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed(open self-aligning ball bearing and Sealed self-aligning ball bearings). The bearings are insensitive to angular misalignment of the shaft relative to the housing

Self-Aligning Ball Bearing

Self-aligning ball bearing has cylindrical hole and tapered hole two kinds of structure, cage material has steel plate, synthetic resin, etc.. Its characteristic is the outer ring raceway is spherical self-aligning ball bearing, with automatic centering, can compensate for the error caused by different heart and shaft deflection, but its inner and outer ring relative tilt shall not exceed 3 degrees.

Self-aligning ball bearing is two raceways of the inner ring and raceway for the spherical outer ring, assembled with a self-aligning ball bearing.

The center of curvature of the outer ring raceway surface is the same as the bearing center, so it has the same adjusting function as the automatic spherical self-aligning ball bearing. When the shaft or housing is deflected, it can be adjusted automatically without increasing the burden on the bearing. self-aligning ball bearings can bear radial load and axial load in two directions. Radial load capacity is large, suitable for situations with heavy load and shock load. The inner ring inner diameter is tapered hole bearing, can be directly mounted. Or it can be mounted on cylindrical shaft by using tightening sleeve and dismantling cylinder. The cage uses steel plate stamping cage, polyamide forming cage and copper alloy turning cage.

Can bear large radial load, but also can bear a certain axial load. This kind of bearing outer ring raceway is spherical, so has the spherical performance, when the shaft is bent or tilted and make the inner ring center line and outer ring center line relative tilt does not exceed 1 ° ~ 2.5 °, the bearing can still work.

Self-aligning ball bearing bore has two kinds of cylindrical and conical. In order to strengthen the lubrication performance of the bearing, the ring-shaped oil groove and three oil holes are processed on the outer ring of the bearing.

Self-aligning ball bearing product characteristics

Mainly bear radial load, at the same time can bear a small axial load. Axial displacement of the shaft (shell) is limited to the clearance limit, with automatic self-aligning performance, allowing the inner and outer relative tilt is not large under the conditions of normal work, suitable for supporting the seat hole can not strictly ensure coaxiality of the components.

Features and benefits of self aligning ball bearing.

– High quality steel – ultra clean steel helps extend bearing life by up to 80%
– Available in pressed steel and polyamide cages
– Advanced grease technology – lubricants that extend grease life and performance
– High-grade balls – smooth and quiet operation even at high speeds
– Super Finished Raceways – refined to minimize noise and improve lubricant life and distribution
– Supply sealed bearings

Self-aligning ball bearing construction forms

Self-aligning ball bearings with dust caps and seals are assembled with the appropriate amount of grease and should not be heated or cleaned before mounting, and do not require relubrication during use. Self aligning ball bearings are mainly used in precision instruments, low-noise motors, automobiles, motorcycles and general machinery, etc. They are used in the machinery industry.

Self-aligning ball bearing working requirements:

For heavy loads, harsh working conditions or special requirements for sealing bearing configurations, built-in contact type sealed ball bearings can be used. These bearings have exactly the same dimensions as non-sealed bearings and can be used in place of non-sealed bearings in many applications. The allowable alignment angle is 0.5°, and the operating temperature is -20℃~110℃. The bearing has been filled with appropriate amount of lithium-based anti-rust grease, and grease can also be added according to user requirements.

Spherical Ball Bearing Type:

According to the difference of inner ring with or without baffle and cage, it can be divided into two basic types, C type and CA type. C type bearing is characterized by inner ring without baffle and steel plate stamping cage, while CA type bearing is characterized by baffle on both sides of inner ring and turning solid cage. This type of bearing is especially suitable for heavy load or vibration load work. Self aligning ball bearings in the inner ring and two raceways for the spherical outer ring, assembled with drum-shaped roller bearings。
