Self-aligning ball bearings are a type of rolling-element bearing that can accommodate misalignment between the shaft and housing without causing damage. This makes them ideal for applications where there may be shaft deflection or mounting errors. The bearings consist of two rows of balls and a common concave sphered raceway in the outer ring. They are commonly used in industrial machinery, automotive applications, and agricultural equipment. These bearings are designed to reduce friction and increase rotational efficiency, making them a reliable choice for a range of applications.

Frequently Asked Questions (FAQs)
1. What is a self aligning ball bearing used for?
Self-aligning Ball Bearings are particularly suitable for applications where misalignment occurs from errors in mounting or from shaft deflection. This bearing should only be used in light axial load applications due to the small axial capacity.
2. How do self aligning linear bearings work?
This self-alignment capability is made possible by the design of the load bearing plates, which can be sharply crowned, gradually crowned, or radiused. Sharply crowned designs use bearing plates that are thinner on the ends than in the middle, allowing the plate to “rock” around a pivot point at its center.
3. Are tapered roller bearings self aligning?
Tapered roller bearings also have static misalignment limitations however, in some applications the bearing housings can be designed so the bearing can self align properly. One of the other disadvantages is with speed limitations.
4. What is a self aligning pillow block bearing?
MRC self-aligning bearings have two rows of balls with a common sphered raceway in the outer ring. This gives the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing.
