The Timken Company 415725 Radial Shaft Oil Seal

The Timken Company 415725 radial shaft oil seal is a radial shaft seal built to retain lubricant and prevent contaminants from entering bearing assemblies in heavy‑duty industrial gearboxes, pumps, conveyors, electric motors, compressors, and mining equipment. It features a Type 41 multi‑lip nitrile (NBR) seal with a steel case and inner case, Redi‑Coat protection, and dimensions: shaft diameter 5.000 in (127.000 mm), outside diameter 6.007 in (152.578 mm), housing bore 6.001 in (152.425 mm), and overall width 0.500 in (12.700 mm). The seal uses a multi‑lip with spring configuration and is rated for a maximum shaft speed of 3000 ft/min and a 7 psi pressure rating, with an operating temperature range from -40°F to 225°F (-40°C to 107°C). Common replacements include SKF 49929, CR 415725, and National 415725, and it is used by maintenance teams, OEMs, and system integrators for preventive maintenance and seal replacement to minimize lubricant leakage and extend bearing life.
