The Timken HM89410 tapered roller bearing cup is a precision single cup (outer ring) designed to be paired with a matching tapered roller bearing cone to support combined radial and axial loads in heavy-duty industrial rotating equipment. This outer ring measures 3.000 in (76.200 mm) in outside diameter and 0.9063 in (23.020 mm) in width, is made from high-grade bearing steel, and belongs to the HM89400 series with the TS (Tapered Single) design. Key dimensions include a maximum housing fillet radius of 0.130 in (3.30 mm), Da 2.91 in (73.90 mm), Db 2.44 in (61.98 mm); weight is 1.4 lb (0.60 kg). Compatible cones are HM89440, HM89443, HM89444, HM89446, HM89448, and HM89449, with common replacements including HM89443/HM89410 and HM89449/HM89410; NTN HM89410 is listed as an equivalent. Common applications include industrial gearboxes, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems that rely on a paired tapered roller bearing cone for reliable operation.
