Self-aligning bearings are a type of bearing that can accommodate misalignment between the shaft and the housing. They are designed to automatically adjust and compensate for angular misalignment, reducing the stress and friction on the bearing. This is achieved through the use of a spherical outer ring or a concave inner ring, which allows the bearing to tilt or swivel within its housing. Self-aligning bearings are commonly used in applications where shaft deflection, misalignment, or shaft flexing is expected, such as in heavy machinery, agricultural equipment, and industrial applications. They help improve bearing performance, reduce wear, and extend the overall lifespan of the bearing system.
