SKF 30308T72/DBC220 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. Boundary plan per ISO 15 / ISO 355: bore d = 40 mm, outside diameter D = 90 mm, width B (or height H) = 25.25 mm.
