The Timken Company 416077 Radial Shaft Oil Seal

The Timken 416077 radial shaft oil seal is a heavy-duty industrial seal designed to retain lubricant and prevent contaminants from entering bearing assemblies in rotating equipment. Built with a Type 41 multi-lip nitrile (NBR) lip configuration and a spring, it provides dependable sealing in gearboxes, pumps, electric motors, conveyors, compressors, and mining equipment where shaft sealing is essential. Maintenance teams, OEMs, and system integrators use this oil seal for preventive maintenance, equipment repair, and seal replacement to minimize lubricant leakage and extend bearing service life. Key specs include shaft diameter 7.125 in (180.975 mm), outside diameter 8.632 in (219.253 mm), housing bore 8.625 in (219.075 mm), and overall width 0.562 in (14.275 mm). The seal uses a steel case with inner case and features Timken's Redi-Coat finish for ready application. It supports up to 3000 ft/min shaft surface speed and up to 7 psi pressure, with misalignment tolerance of 0.015 in at 800 rpm and 0.010 in at 4200 rpm, and an operating temperature range of -40°F to 225°F (-40°C to 107°C). Common replacements include SKF 71245, CR 416077, and National 416077. Applications span heavy-duty industrial sealing needs in gearboxes, pumps, electric motors, conveyors, compressors, and other rotating equipment where lubricant retention and protection against dust, dirt, and moisture enhance equipment reliability.
