The Timken Company 415350 Radial Shaft Oil Seal

The Timken Company 415350 Radial Shaft Oil Seal is a heavy‑duty, industrial radial shaft seal designed to retain lubricant and exclude contaminants in rotating equipment. It uses a Type 41 multi‑lip nitrile construction with a spring, providing reliable sealing for gearboxes, pumps, electric motors, conveyors, compressors, and other heavy‑duty machinery where shaft sealing is critical. The seal features a 2.187 in (55.550 mm) shaft bore, an outside diameter of 3.628 in (92.151 mm), a housing bore of 3.623 in (92.020 mm), and an overall width of 0.468 in (11.890 mm), housed in a steel case with an inner case and Redi‑Coat protection. It is rated for up to 3000 ft/min shaft surface speed and an operating temperature range from -40°F to 225°F (-40°C to 107°C). Misalignment tolerance is 0.015 in at 800 rpm and 0.010 in at 4200 rpm, reflecting suitability for demanding applications. This part is commonly employed by maintenance teams, OEMs, and system integrators for preventive maintenance, equipment repair, and seal replacement to minimize lubricant leakage and extend bearing life. Common replacements include SKF 415350, CR 415350, and National 415350.
