It is recommend by China BRG bearings that NSK self-aligning ball bearings are suitable when it comes to alignment of the shaft and housing is difficult and the shaft may flex.

By virtue of its internal geometry, NSK self-aligning ball bearings are capable of accommodating small angular misalignments between the shaft and housing. This is achieved by using two rows of balls that run in parallel inner ring raceways and a full width, spherical outer ring raceway. However, caution must be exercised when thrust loads have to be accommodated as these bearings have very little axial load carrying capacity.

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 no rmal loads. However, depending on the surrounding structure, such an angle may not be possible

The Features and Benefits of NSK self-aligning ball bearings are as follows:

1.   High quality Steel – Ultra clean steel to extend bearing life by up to 80%.
2.   Advanced Grease Technology – NSK lubricants that can extend grease life and perfo rmance.
3.   High Grade Balls – Quiet and smooth operation even at high speed.
4.   Super Finished Raceways – Specially honed to minimise noise and improve lubricant distribution and life.
5.   Sealed versions available

For we can supply a full line of NSK self-aligning ball bearings in various tpyes and sizes which is too many to list all of them below, therefore I just list a couple of bearings for reference, more details please feel free to contact with us.
