Timken Metric Series ISO Bearings

Metric-series tapered roller bearings, organised by ISO dimensional series and identified by exact bearing number.

These single-row bearings use metric bore, outside diameter and width, and carry combined radial and axial loads. Series numbers can look similar while dimensions and load ratings differ, so confirm the complete reference and boundary dimensions before ordering. For metric references from a second authorised source, see the KOYO range.

George Lodge Direct is an authorised Timken distributor and can identify the correct bearing for existing equipment. Imperial, sealed and specialist options sit in the wider tapered roller bearings range, alongside our full bearings range.

Series Numbers and Suffixes

Series numbering: The leading digits set the relationship between bore, outside diameter and width. A 302 series bearing differs in width and load rating from a 322 of the same bore.

Suffixes: Denote tolerance class, internal clearance or cage design. A reference with a suffix is not the same specification as the base number.

Cross-manufacturer fit: Boundary dimensions are standardised, but internal geometry is not.
