The Timken Company HM516410 Tapered Roller Bearing Cup

The Timken HM516410 tapered roller bearing cup is a precision single cup (outer ring) designed for use with a matching tapered roller bearing cone to support combined radial and axial loads in heavy-duty industrial rotating equipment. Commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems where reliable bearing performance and long service life are essential, it pairs with Timken HM516442, HM516445, or HM516449 cones for complete bearing assemblies. Key specifications include outside diameter 5.2500 in (133.350 mm), outer ring width 1.2813 in (32.545 mm), material: high-grade bearing steel, weight 4.7 lb (2.1 kg), maximum housing fillet radius 0.130 in (3.30 mm), and housing backing shoulder diameters Da 5.08 in (129.00 mm) and Db 4.65 in (118.11 mm). It is part of the HM516400 series (Design Series TS) and is commonly used in heavy-duty gear reducers, conveyors, mining and aggregate equipment, and other power transmission applications when mated with the specified Timken cones; common replacements include HM516442/HM516410 and HM516449/HM516410 bearing sets, with NTN HM516410 listed as an equivalent.
