Self Aligning Ball Bearings- Cylindrical / Tapered / Sealed
Self Aligning Ball Bearings has a spherical outer raceway. The center of this raceway coincides with the center of the bearing itself. Due to this specific design the rolling elements rotate and align themselves in the event they are misaligned.
Self Aligning Ball Bearings are very useful in applications where there is a displacement of the centers around the shaft and housing rotate and deflection are likely to occur. Self aligning bearings come in a pressed steel cage, snap-type steel cage and copper alloy machined cages.

Features And Benefits Of Self Aligning Ball Bearings
- Self-aligning ball bearings are rated at low minimum load specifications.
- Spherical outer ring raceway allows self-alignment, accommodating shaft or housing deflection, and misaligned mounting conditions.
- Tapered bore design can be mounted readily using an adapter.
- Self-aligning ball bearings are a great way to reduce the noise and vibration levels for instance, in fans.
Application And Uses Of Self Aligning Ball Bearings
- Self-aligning ball bearings produce less friction than other kinds of rolling bearings, which allows them to run cooler even at speeds that are high.
- This type of bearing is most commonly used in the machinery industry, industrial fans, agriculture, etc.
