Timken HM212011 Tapered Roller Bearing Cup

The Timken HM212011 tapered roller bearing cup is a single outer-ring cup used in tapered roller bearing systems to support combined radial and axial loads in heavy-duty rotating equipment. Designed to pair with a compatible tapered roller bearing cone, such as HM212049 or HM212046, it provides precise load distribution and dependable shaft support in industrial gearboxes, mining equipment, conveyors, construction machinery, and other heavy-duty power transmission applications. Key specifications include an outside diameter of 4.8125 in (122.238 mm), outer ring width of 1.1700 in (29.718 mm), ABMA Class 2 precision, and construction from high-grade bearing steel, with a maximum housing fillet radius of 0.130 in (3.30 mm). Part of the HM212000 design series (TS), this cup is commonly used in gear reducers, material handling equipment, mining and quarry machinery, construction equipment, and other rotating systems requiring reliable radial and axial support.
