The 323 series comprises metric single-row tapered roller bearings with a large contact angle and outstanding axial load-carrying capacity, capable of withstanding substantial radial and unidirectional axial combined loads. They typically feature stamped steel cages and offer good interchangeability across standard sizes. When fitted in pairs, they can withstand bidirectional axial loads and are suitable for applications involving high impact loads. They are commonly used in heavy-duty transmission components such as heavy goods vehicles, mining machinery, large gearboxes and construction machinery.
