Self-aligning roller bearings are a type of rolling bearing with self-aligning capability, capable of carrying both radial and axial loads, and are widely used in heavy-load and vibration environments.
Definition and Structure
Self-aligning roller bearings are specially designed rolling bearings with a double-row roller structure. Their outer ring has a common spherical raceway, while the inner ring has two raceways inclined relative to the bearing axis. This design allows self-aligning roller bearings to automatically adjust for angular misalignment, accommodating installation errors between the shaft and housing or shaft bending deformation.
