Self - Aligning Ball Bearing
Bearing Feature of Self - Aligning Ball Bearing
Spherical Ball Bearing is mainly applied on high speed, high precision and little axial load occasions, such as airplane engine main shaft, machine tool main shaft and main shafts of other high speed precision machine. It can also be applied on high frequency motor, steam turbine, oil pump, air compressor and printing machine etc. It is one of the bearings most widely used in machinery industry.
Applications of Self - Aligning Ball Bearing:
Spherical ball bearings are suitable for bearing heavy loads and impact loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar extraction and other industries and general machinery, etc

We produces self-aligning ball bearings to several designs. These are
open bearings of the basic design
sealed bearings
open bearings with an extended inner ring
This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.
