What is Self-aligning ball bearing
Self-aligning ball bearings have two structures: cylindrical bore and tapered bore, and the cage is made of steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical, with self-alignment, which can compensate for the errors caused by misalignment and shaft deflection, but the relative inclination of the inner and outer rings should not exceed 3 degrees.
A self-aligning ball bearing is a bearing equipped with spherical balls between the inner ring of two raceways and the outer ring whose raceways are spherical.
The center of curvature of the raceway surface of the outer ring of the self-aligning ball bearing is consistent with the bearing center, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft or housing is deflected, it can be adjusted automatically without increasing the bearing burden. Spherical roller bearings can bear radial load and axial load in two directions. Large radial load capacity, suitable for heavy load and shock load. The inner diameter of the inner ring is a bearing with a tapered bore, which can be directly installed. Or use an adapter sleeve or a disassembly tube to install it on the cylindrical shaft. The cage uses a steel stamping cage, a polyamide forming cage, and a copper alloy car cage.

It can withstand large radial loads and at the same time can withstand certain axial loads. The outer ring raceway of this type of bearing is spherical, so it has self-aligning performance. When the shaft is bent or tilted and the centerline of the inner ring and the centerline of the outer ring is not more than 1°~2.5°, the bearing can still work.
The inner hole of the self-aligning ball bearing has two types: cylindrical and conical. The taper of the conical inner hole is 1:12 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.
Product features of self-aligning ball bearings
Mainly bear radial load, and can bear small axial load at the same time. The axial displacement of the shaft (housing) is limited within the clearance limit, and it has self-aligning performance. It allows normal operation under the condition that the inner and outer sides are not relatively inclined. It is suitable for parts where the support seat hole cannot strictly guarantee coaxiality.
Self-aligning ball bearing structure
The self-aligning ball bearing with dust cover and the sealing ring have been filled with an appropriate amount of grease during assembly. It should not be heated or cleaned before installation. There is no need to relubricate during use. It is suitable for operating temperature -30 ℃ to + 120 ℃ between. The main purpose of self-aligning ball bearings: suitable for precision instruments, low-noise motors, automobiles, motorcycles, and general machinery, etc. It is the most widely used type of bearing in the machinery industry
Application of self-aligning ball bearing
Self-aligning ball bearings are suitable for bearing heavy loads and shock loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar crushing, and other industries and general machinery.
