SKF 39580 tapered roller bearing cone — the inner ring complete with its tapered roller and cage assembly, in the inch 39500 series. Bore 2.2500 in (57.150 mm), cone width 1.1875 in (30.163 mm). Carburized bearing steel races with a pressed steel cage.
39580 is the industry cone number, carried identically by Timken, NTN, Koyo and Bower. The carton also shows the form BR 39580, where BR is SKF’s prefix for its inch tapered roller range. The number fixes the cone envelope, so every brand’s 39580 shares the same bore, width and roller path.
Straight bore, tapered raceway. A tapered roller cone carries radial load and thrust in one direction simultaneously, the split between the two being set by the raceway angle. The 39500 series is a medium-width inch series used on wheel ends, gearbox shafts and pinion supports.
Cone only, two pieces. The matching cup is the 39520.
The cone seats as a press fit on the shaft and the cup as an interference or line fit in the housing. Endplay or preload is set by axial adjustment once both halves are seated and the rollers have been run in against the cup raceway. Oil bath, circulating oil and grease lubrication all apply.
Timken 39580, NTN 39580, Koyo 39580 and Bower 39580 are the same cone and interchange directly. The 39520 cup is the published counterpart; cone and cup raceway angles are matched between the two halves of a given set number.
