Timken Tapered Roller Bearings Guide
Product description
The 28580 / 28521-B Timken TSF tapered roller bearing features a single-row tapered roller bearing design with a flanged outer ring. The flange provides accurate axial positioning of the outer ring within the housing, while through-bored housing designs help achieve precise alignment of the bearing seats. This configuration simplifies installation and improves mounting stability in applications requiring reliable positioning and consistent operating performance.
The 28580 / 28521-B TSF bearing is widely used in industrial equipment, gearboxes, agricultural machinery, construction machinery, and other applications where accurate bearing location, reliable load support, and long service life are required.
