The Timken Company 415009N Radial Shaft Oil Seal

The Timken National 415009N is a radial shaft oil seal designed to retain lubricant and exclude contaminants in heavy industrial rotating equipment. It uses a Type 41 multi-lip seal with a loaded spring and ACM/polyacrylate lip material, housed in a steel case with inner case, and is Redi-Coat ready for faster installation. Designed for gearboxes, pumps, electric motors, conveyors, compressors, and other rotating machinery, it provides reliable lubricant retention and protects bearings from dust and moisture. Key dimensions include a shaft diameter of 2.750 in (69.850 mm), outside diameter of 3.881 in (98.577 mm), housing bore of 3.876 in (98.450 mm), and overall width of 0.468 in (11.887 mm). It supports up to 3000 ft/min shaft surface speed and operates from -20°F to 300°F (-29°C to 149°C). In practice, maintenance teams, OEMs, and system integrators use this seal for preventive maintenance and seal replacement to minimize leakage and extend bearing life; compatible replacements include SKF 415009N, CR 415009N, and National 415009N.
