● Self aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. 

The center of curvature of the outer raceway surface is identical to the center of the bearing, so it has the same self-aligning function as the self aligning ball bearing.

When the shaft and outer casing are deflected, they can be adjusted automatically without increasing the bearing load. Spherical ball bearings can withstand both radial and axial loads in both directions. In addition to its large radial load capacity, it is suitable for heavy load and impact loads. The inner ring inner diameter has a tapered bore bearing and can be mounted directly. The cylindrical shaft can also be mounted with the adapter sleeve and removal cylinder.

The cage uses steel stamping cage, polyamide forming cage and copper alloy cage.

In addition to withstanding large radial loads, this bearing has a self-aligning outer ring raceway that is spherical. Despite the shaft being bent or tilted, the bearing can still function if the center line of the inner ring is inclined by no more than 1° to 2.5° relative to the center line of the outer ring.

The inner diameter of the customized self-aligning ball bearing is cylindrical or conical. The conical inner bore has a taper of 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.As a professional self aligning ball bearing supplier & manufacturer, JNSN Bearing has been specialized in customized self-aligning ball bearing for over 20 years.Want to know more about self aligning ball bearing, contact us.

● Bearing features

Accommodate static and dynamic misalignment

The bearings are self-aligning like spherical roller bearings or CARB bearings.

● Excellent high-speed performance

Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.

● Minimum maintenance

Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.

● Low friction

Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.

● Excellent light load performance

Self-aligning ball bearings have low minimum load requirements.

● Low noise

Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.
