Timken H913810 Tapered Roller Bearing Cup Outer Race

The Timken H913810 is a single tapered roller bearing cup (outer race) designed to be paired with Timken H913800-series cones to form a complete tapered roller bearing assembly that supports heavy combined radial and axial loads. Made from through-hardened bearing steel and sold as an open cup, it requires external lubrication and is intended to be used with a matching cone assembly, delivering precise shaft positioning and durable load distribution in demanding industrial environments. Key specs include a Cup Outside Diameter of 5.7500 in (146.050 mm), Cup Width of 1.0000 in (25.400 mm), and a geometry factor (Cg) of 0.0927, with a single-row design in the TS (Tapered Single) cup style and imperial design units; it weighs approximately 6.3 lb (2.9 kg). It is compatible with Timken cones such as H913840 and H913843, and its housing features include a maximum fillet radius of 0.130 in (3.30 mm) and backing shoulder diameters of 5.46 in (138.68 mm) frontface and 4.88 in (123.95 mm) backface. Applications span industrial gearboxes, mining equipment, heavy-duty axles, construction machinery, conveyors, and material handling systems, where high radial and thrust load capacity and reliable operation are essential. Common replacements include NTN H913810, SKF H913810, and KOYO H913810.
