22321 Spherical Roller Bearing
22321 is a double row spherical roller bearing with a 105 mm bore, 225 mm outer diameter and 81 mm width, built to the ISO 15 boundary dimensions of the 22300 series. It is the largest size in the series. It carries heavy radial load and tolerates shaft misalignment, which suits shock-loaded equipment and applications where alignment cannot be held in service.
Because the boundary dimensions are fixed by ISO 15, the 22321 is interchangeable with SKF 22321, NSK 22321, FAG 22321 and NTN 22321: it fits the same 105 mm shaft and the same housing bore. Cage material, internal clearance, precision grade and sealing differ between makers and should be confirmed against the application before substitution.
