Timken HM905843 Tapered Roller Bearing Cone Inner Ring Assembly

The Timken HM905843 tapered roller bearing cone is a precision single-cone inner ring assembly engineered to support both radial and axial loads in heavy-duty rotating equipment. It is designed to be paired with the Timken HM905810 tapered roller bearing cup for complete bearing sets and is commonly installed in industrial gearboxes, conveyors, mining and aggregate equipment, construction machinery, agricultural machinery, and other power transmission systems requiring reliable shaft support. This bearing cone belongs to the HM905800 series with the TS design series, and features a bore of 1.7712 in (44.988 mm) and an inner ring width of 1.2500 in (31.750 mm). It uses a stamped steel cage and is made from high-grade bearing steel to handle combined radial and axial loads, with a dynamic radial load rating of 30,300 lbf (135,000 N) and a static radial load rating of 38,400 lbf (171,000 N). The maximum shaft fillet radius is 0.100 in (2.540 mm), and the assembly weighs 3.0 lb (1.4 kg). Compatible cup: Timken HM905810; common replacements include HM905810, HM905843/HM905810 bearing set, and NTN HM905843 equivalent.
