Performance and characteristics of self-aligning ball bearings
Self aligning ball bearings are a special type of rolling bearing, with a spherical outer raceway and automatic centering function. This type of bearing can compensate for errors caused by different eccentricities and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees. The following are the main performance and characteristics of self-aligning ball bearings:

Automatic centering: The outer raceway of the centering ball bearing is spherical, thus it has automatic centering performance. This means that when the shaft or housing bends, the bearing can automatically adjust without increasing the bearing burden

Load bearing capacity: Self aligning ball bearings can withstand large radial loads and also withstand certain axial loads. They are particularly suitable for situations with heavy loads and impact loads

Service life: The service life of self-aligning ball bearings is relatively long, thanks to their excellent materials and manufacturing processes

Sealing performance: Self aligning ball bearings usually have good sealing performance, which can prevent dust and dirt from entering the interior of the bearing, and also reduce the leakage of lubricating grease

Applicability: Self aligning ball bearings are suitable for a wide range of fields such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. They are particularly useful for applications that may result in significant axial deflection or misalignment
Structural form: The self-aligning ball bearing has two structural forms: cylindrical hole and conical hole. The taper of the conical hole is usually 1:12 or 1:30, which helps to enhance the lubrication performance of the bearing,

Friction and temperature rise: Compared with other types of rolling bearings, self-aligning ball bearings generate lower friction and relatively lower temperature rise even at high speeds. This is because the clearance between the rolling elements and the outer ring can reduce friction and the heat generated by friction
Minimum load requirement: Self aligning ball bearings have lower minimum load requirements, which means they can better maintain the rolling state of the bearing and reduce harmful sliding between the ball and the raceway during high-speed operation.

In summary, self-aligning ball bearings have been widely used in the industrial field due to their automatic self-aligning, high load-bearing capacity, long service life, good sealing performance, and wide applicability.
