The Timken Company 417493 Radial Shaft Oil Seal

The Timken 417493 radial shaft oil seal is a spring-loaded, Type 41 multi-lip seal that retains lubricants and blocks contaminants in rotating equipment such as industrial gearboxes, pumps, electric motors, conveyors, and compressors. Built with a nitrile (NBR) sealing element inside a steel case with inner case, it features Timken's Redi-Coat coating for protection and easier handling, and uses a multi-lip configuration with a spring to minimize leakage. Key dimensions include shaft diameter 3.437 in (87.300 mm), outside diameter 4.631 in (117.627 mm), housing bore 4.626 in (117.500 mm), and overall width 0.500 in (12.700 mm); it supports up to 3000 ft/min shaft surface speed and operates from -40°F to 225°F (-40°C to 107°C). With a 7 psi pressure rating and misalignment tolerance of 0.015 in at 800 rpm and 0.010 in at 4200 rpm, this general-purpose industrial seal is used in machinery such as pumps, reducers, conveyors, and electric motors, and is commonly cross-referenced as SKF 34338, CR 417493, or National 417493.
