The Torrington Company IR-202416 Needle Roller Bearing

The Torrington IR-202416 needle roller bearing inner ring is a precision-ground, hardened inner race designed for use with heavy-duty needle roller bearings when the shaft cannot serve as the raceway. As part of the IR Inch Series, it features a 1.2500 in bore (31.750 mm), 1.5000 in outside diameter (38.100 mm), and 1.0000 in width (25.400 mm), constructed from hardened high-carbon chrome steel with a precision-ground raceway. This separable inner ring includes an oil groove and lubrication hole (standard on 6-digit IR series) and a minimum chamfer radius of 0.060 in, designed to pair with heavy-duty needle roller bearings such as the HJ-243316. Common applications include industrial gearboxes, transmissions, hydraulic equipment, machine tools, agricultural machinery, and other rotating equipment where a hardened shaft is impractical, making it suitable for equipment repairs, bearing replacements, machine rebuilds, and drivetrain retrofits.
