NSK self aligning ball bearing

NSK self aligning ball bearing features
Self aligning ball bearing can bear large radial load and certain axial load at the same time. The outer race raceway of this kind of bearing is spherical, so it has centering performance. When the shaft is bent or tilted by force, the relative inclination between the inner race center line and the outer race center line is no more than 1 ° ~ 2.5 °, the bearing can still work.
The inner holes of self-aligning ball bearings are cylindrical and conical. The taper of conical inner hole is 1:1 2 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three evenly distributed oil holes are machined on the outer ring of the bearing.
NSK self-aligning ball bearing structure
The self-aligning ball bearing with dust cover and sealing ring has been filled with an appropriate amount of grease during assembly. It should not be heated or cleaned before installation. It does not need to be lubricated during use. It is suitable for the operating temperature between - 30 ℃ and + 120 ℃.
Application of NSK self-aligning ball bearing
Main uses of self-aligning ball bearing: it is suitable for precision instruments, low-noise motors, automobiles, motorcycles and general machinery. It is a kind of bearing widely used in the machinery industry.
