The Timken Company 417501 Radial Shaft Oil Seal

The Timken Company 417501 Radial Shaft Oil Seal is a steel-cased, multi-lip, spring-loaded seal designed to retain lubricants and prevent contaminants from entering rotating equipment such as industrial gearboxes, pumps, electric motors, conveyors, and compressors. This Type 41 seal from Timken’s 410000 series uses a nitrile (NBR) sealing element with a spring-loaded, multi-lip configuration to minimize lubricant leakage and extend bearing life. Key dimensions include a shaft diameter of 3.687 in (93.650 mm), outside diameter of 4.756 in (120.802 mm), housing bore of 4.750 in (120.650 mm), and an overall width of 0.500 in (12.700 mm), with a steel case and inner case construction and Redi-Coat finish. It supports up to 3000 ft/min shaft surface speed, tolerates misalignment of 0.015 in at 800 rpm and 0.010 in at 4200 rpm, and operates from -40°F to 225°F (-40°C to 107°C) at up to 7 psi.
