Self Aligning Ball Bearings of the Series 12
With the swivelling inner ring, the self aligning ball bearings 1202 offers excellent alignment error compensation. With the two rings of barrel-shaped rollers, it can absorb high radial forces. Main dimensions according to DIN 630.
The special feature of this series
Main dimensions according to DIN 630. Self-aligning ball bearings of the series 12 have smaller dimensions than self-aligning ball bearings of the series 13 with the same inner diameter, (self aligning bearing size chart) whereof results in a lower weight. From 17 millimetre inner diameter on, they are also available with tapered bore (for fixing the adapter sleeve). They are open, can thus be regreased easily and can be used in case of a high rotational speed.

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, which can be caused, for example, by shaft deflection.
- 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.
Available brands: INA/FAG, KOYO, NSK, SKF, NTN-SNR, IKO, NACHI, TIMKEN, different suffixes are assigned according to their characteristics. Please pay attention to the bearing comparison table (see more information). In addition, to meet the special needs of the equipment, we accept bearing customization to meet your specific needs.
When to use self-aligning bearings?
Self-aligning bearings are designed for applications where misalignment or angular displacement between the shaft and the bearing housing is expected. Misalignment can be adjusted inside or outside the bearing.
How do self aligning ball bearing work?
Often referred to as the “ideal” ball, we demystify how self-aligning bearings run and share their multiple uses.
Have you ever wondered what self-aligning ball bearings and roller bearings, or other custom solutions to distinguish? How exactly do these bearings self-align? These little wonders are often recommended and designed to be placed in the application; otherwise, there is a dislocation. Assembly errors may come from misalignment, deflection, machine errors or other manufacturing defects.
Self-aligning bearing design has so many uses in the game. Self-aligning ball bearings include two volleyball and a spherical outer ring.
This unique ball bearing outer race (sometimes doubling in the self-aligning bearing) can self-align and run smoothly without causing any stress on bearings. As it involves a roller, these units can be run faster than the other bearing. These bearings have many variations, making them essential goods in your industry.
Self aligning ball bearings are often used in the following industries:
