The Timken Company 415876 Radial Shaft Oil Seal

The Timken National 415876 radial shaft oil seal is designed to retain lubricant and prevent contaminants from entering bearing assemblies in heavy-duty rotating equipment. Built as a Type 41, 410000-series multi-lip seal with a nitrile (NBR) lip and a steel case with inner case, it includes Redi-Coat protection for quick corrosion resistance. Suitable for industrial gearboxes, pumps, electric motors, conveyors, compressors, and mining equipment, this seal handles a shaft diameter of 7.000 in (177.800 mm), an outside diameter of 9.321 in (236.753 mm), a housing bore of 9.313 in (236.550 mm), and an overall width of 0.625 in (15.875 mm). It supports a maximum shaft surface speed of 3000 ft/min and tolerates misalignment of 0.015 in at 800 rpm and 0.010 in at 4200 rpm. The operating temperature range is -40°F to 225°F (-40°C to 107°C). This part is a common replacement for SKF 415876 and National 415876, and is widely used by maintenance teams, OEMs, and system integrators for preventive maintenance and seal replacement to minimize lubricant leakage and extend bearing life.
