What type of bearing accommodates slight angular misalignment?

A self-aligning bearing is specifically designed to accommodate slight angular misalignment between the shaft and housing. This type of bearing features an outer ring that can pivot, allowing the inner ring and rolling elements to remain in proper contact despite misalignment. This design helps distribute the load evenly and reduces wear on the bearing components, contributing to a longer lifespan and improved performance in applications where alignment may not always be perfect.

In contrast, cylindrical bearings and deep groove ball bearings are typically rigid and do not accommodate angular misalignment effectively. They are best suited for applications where shafts are well-aligned. Plain bearings, while they can handle some deflection, do not have the same level of self-alignment features as self-aligning bearings, making them less suitable for applications where misalignment is a concern. This is why the self-aligning bearing is the correct choice for accommodating slight angular misalignment.
