Self Aligning Ball Bearings Description

Our comprehensive collection of Self Aligning Ball Bearings provides the ultimate solution for applications where shaft alignment is difficult to maintain or where shaft deflection occurs under load. Featuring a double-row design with a common spherical raceway in the outer ring, these bearings allow the inner ring and ball assembly to tilt freely, automatically correcting misalignments of up to 2.5 degrees without increasing friction or heat. This extensive category covers the light-duty 1200 and 2200 series, the robust 1300 and 2300 series for higher load capacities, and specialized Miniature series for precision instruments. We offer various configurations, including cylindrical bores for direct mounting, tapered bores (K series) for use with adapter sleeves, and sealed versions (2RS) for maintenance-free operation in harsh environments. Known for having the lowest friction of all rolling bearings, our self-aligning range ensures cool running at high speeds and extended service life for textile machinery, agricultural equipment, conveyor systems, and precision mechanical drives.
