The 322 series comprises metric single-row tapered roller bearings with a medium contact angle, capable of withstanding combined radial and unidirectional axial loads. Most are fitted with stamped steel cages and feature standardised dimensions and good interchangeability. When mounted in pairs in opposite directions, they can withstand bidirectional axial loads and are widely used in automotive transmission systems, construction machinery, gearboxes, mining equipment and agricultural machinery under medium to heavy load conditions.
