Timken 7210WN SU Angular Contact Ball Bearing

The Timken Fafnir 7210WN SU is a single-row angular contact ball bearing engineered for high-speed equipment that must carry combined radial and axial loads. It features a 40° contact angle and universal SU mounting for duplex arrangements in machine tool spindles, industrial gearboxes, pumps, compressors, electric motors, and other precision machinery where shaft guidance and speed stability matter. Key specs: bore diameter 50 mm, outside diameter 90 mm, width 20 mm; dynamic radial load rating 9,500 lbf (42,500 N); static radial load rating 6,400 lbf (28,400 N); limiting speed with grease 4,300 rpm and with oil 5,700 rpm. The cage is a ball piloted pressed brass design, and the bearing is designed for high-speed operation with precise shaft alignment. Common replacements include SKF 7210 BECBM, NSK 7210AW, and NTN 7210U.
