Timken HJ-263516 Needle Roller Bearing Assembly

Description:

The Timken HJ-263516 needle bearing with IR-222620 inner ring is a heavy-duty caged needle roller bearing assembly used to provide high radial load capacity in compact industrial power transmission and rotating equipment. Commonly installed in industrial gearboxes, transmissions, machine tools, hydraulic equipment, pumps, and construction machinery where space-saving bearing designs are required. Maintenance teams, OEMs, and system integrators use this bearing assembly for equipment repair, bearing replacement, machine rebuilds, and drivetrain maintenance.

Applications:

The Timken HJ-263516 needle bearing is designed for industrial applications requiring high radial load capacity with a compact cross-section. When paired with a hardened inner ring, it provides reliable shaft support in gear reducers, hydraulic systems, machine tools, agricultural equipment, conveyors, and other rotating machinery operating under demanding load conditions. Note: Timken catalogs typically pair the HJ-263516 bearing with the IR-212616 inner ring; the IR-222620 inner ring is generally associated with the wider HJ-263520 bearing. Verify compatibility before installation.
