SKF 1210K C3 Self-Aligning Ball Bearing Double Row

SKF 1210K C3 self-aligning ball bearing is a double-row unit designed to tolerate shaft misalignment while delivering smooth, quiet rotation under heavy loads. This 50x90x20 mm bearing has a 50 mm bore, 90 mm outer diameter, and 20 mm width, offering a compact footprint for a wide range of industrial applications. The C3 radial clearance class indicates greater than normal internal clearance to accommodate shaft deflection, mounting tolerances, and thermal expansion. Its double-row arrangement uses two rows of balls mounted on an inner ring with a common spherical outer race, enabling self-alignment and reducing the risk of binding when misalignment or bending occurs. Typical uses include conveyors, mining and processing machinery, agricultural equipment, and other heavy-duty drives where shaft alignment cannot be guaranteed. Confirm compatibility with housing and shaft tolerances per SKF catalog guidance to ensure proper fit and reliable performance.
