SKF 31318/DF — Matched pair / set of tapered roller bearings
SKF · Bearings & Power Transmission · Matched Tapered Roller Bearings
SKF 31318/DF matched pair / set of tapered roller bearings. Factory-matched pair (TDO / 2S / 3S) or set of tapered roller bearings, pre-selected so the assembled axial or radial internal clearance falls in a controlled band. Suitable for gearbox pinion shafts, marine propeller-shaft thrust bearings, wheel-hub bearings. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options.
