Timken HJ-263516 Needle Roller Bearing Assembly

Timken HJ-263516 needle bearing assembly with IR-222620 inner ring is a heavy-duty, caged, single-row needle roller bearing designed to deliver high radial load capacity in a compact cross-section. This assembly is commonly used in industrial gearboxes, transmissions, machine tools, hydraulic equipment, pumps, and construction machinery where space-saving bearing designs are required. It features a steel riveted cage, bore 1.6250 in (41.275 mm), outside diameter 2.1875 in (55.563 mm), and width 1.000 in (25.400 mm). The bearing delivers a dynamic load rating of 48.5 kN and a static load rating of 76.5 kN, with a limiting speed of 7,000 rpm under grease lubrication or 11,000 rpm with oil lubrication. It adheres to Military Standard MS 51961. For compatibility, Timken catalogs typically pair this bearing with IR-212616 inner rings; the IR-222620 inner ring is generally associated with the wider HJ-263520 bearing, so verify fit before installation. This needle bearing assembly is used for shaft support in gear reducers, hydraulic systems, conveyors, and rotating machinery operating under demanding load conditions, and is used during equipment repair, machine rebuilds, and drivetrain maintenance.
