The 320 series comprises metric single-row tapered roller bearings with a separable design, facilitating easy installation and removal. With a small contact angle, they can withstand combined radial and unidirectional axial loads. They feature a compact design, narrow width and good limiting speeds. They typically feature stamped steel cages, offering high interchangeability; when fitted in pairs, they can withstand bidirectional axial loads. They are widely used in applications with limited space and moderate loads, such as automotive wheel hubs, gearboxes, agricultural machinery, and small to medium-sized reduction gearboxes.
