Timken National 415041 Oil Seal

The Timken National 415041 oil seal is a heavy-duty industrial radial shaft seal engineered to retain lubricant and prevent contaminants from entering bearing assemblies in rotating equipment. Built with a Type 41 multi-lip with spring lip configuration, lip material is nitrile (NBR), and the assembly uses a steel case with inner case, complemented by Redi-Coat for ease of handling and corrosion resistance. Key specifications include MPN 415041, Series 410000, shaft diameter 4.000 in (101.600 mm), outside diameter 5.756 in (146.202 mm), housing bore 5.751 in (146.075 mm), and overall width 0.562 in (14.275 mm). The seal supports a maximum shaft surface speed of 3000 ft/min and operates from -40°F to 225°F (-40°C to 107°C). It is intended for general-purpose industrial shaft sealing and is commonly used in gearboxes, pumps, electric motors, conveyors, compressors, and other rotating machinery in heavy-duty power transmission applications to reduce lubricant leakage and extend bearing life. Common replacements include SKF 40108, CR 415041, and National 415041.
