Features: (1) When the important official shell will flex, it can be automatically adjusted and aligned without increasing the bearing burden. (2) Self-aligning ball bearings have large radial bearing capacity and are mainly suitable for heavy load and impact load. (3) Good seismic performance and long service life. (4) Good sealing performance; (5) The concentricity error caused by machining, installation and shaft deformation can be compensated. Application: Self-aligning ball bearings are mainly suitable for bearings that can cause considerable shaft deflection or misalignment, such as fine appearance, low noise motors, automobiles, motorcycles, woodworking machinery, textile machinery, mining machinery, electromechanical equipment, plastic machinery, working instruments, medical instruments, fitness equipment and transmission shafts of general machinery. Bearings are widely used, and different types of bearings are on platforms such as Moby and Zhenkun.
