Self-aligning ball bearings

Self-aligning ball bearing

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 bearings are insensitive to angular misalignment of the shaft relative to the housing (fig. 1), which can be caused, for example, by shaft deflection.

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.

Highlights

SKF extends service life by more than 3 times in textile processing machine

Read how Nahar Industrial Enterprises Ltd., faced with costly and recurring guide roller bearing failures in a range of pretreatment machines, looked to SKF for a solution. Learn how SKF new custom-designed self-aligning ball bearings have been operating trouble-free for 12 months, extending bearing life by more than 3 times.

SKF self-aligning solution for a higher quality paper finish

With an optimized ball set, self-aligning ball bearings can be used in the super calendar section of a paper machine. These bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.

Sealed self-aligning ball bearings

For trouble-free operation, SKF offers sealed self-aligning ball bearings in the 22 and 23 series.

Sealed bearings have a contact seal on both sides that is made of oil and wear-resistant NBR and reinforced with a sheet steel insert (designation suffix 2RS1).

Sealed self-aligning ball bearings are lubricated for the life of the bearing.

SKF self-aligning solution for textile spinning machine

Spindles for spinning yarn require high accuracy, high speed, reliable self-aligning properties and low maintenance.

SKF self-aligning ball bearings are the appropriate solution for this application. They generate very low friction and can run at high speeds. They have the required self-aligning capabilities and are highly reliable.
