1212EKTN9 Self-aligning ball bearing with tapered bore

What is a self-aligning ball bearing?

This type is constructed with the inner ring and ball assembly contained within an outer ring which has a spherical raceway. Due to the construction, this bearing type will tolerate a small angular misalignment from deflection or mounting error. Self-aligning ball bearings are suitable for long shafts where accurate positioning of housing bores is difficult. This type is often used in conjunction with pillow blocks. Cages are made from pressed steel or polyamide resin. This bearing should only be used in light axial load applications due to the small axial support of the rolling elements by the outer ring raceway.

Bearing features

1).Accommodate static and dynamic misalignment

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

2).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.

3).Minimum maintenance

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

4).Low friction

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

5).Excellent light load performance

Self-aligning ball bearings have low minimum load requirements.

6).Low noise

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