The Timken Company 417223 Radial Shaft Oil Seal

The Timken 417223 Radial Shaft Oil Seal is a spring-loaded Type 41 multi-lip seal that retains lubricants and blocks contaminants from entering rotating equipment. Built with a steel case (inner case) and a nitrile (NBR) sealing element, it features Timken’s Redi-Coat finish for ready-to-install service. Commonly used in general-purpose industrial shaft sealing for gearboxes, pumps, electric motors, conveyors, and compressors, it helps extend bearing life and reduce maintenance by minimizing leakage. Key dimensions include a 4.000 in shaft diameter (101.600 mm), 6.256 in outside diameter (158.902 mm), 6.250 in housing bore (158.750 mm), and 0.500 in overall width (12.700 mm). The seal supports up to 3000 ft/min shaft surface speed and a 7 psi pressure rating, and operates in temperatures from -40°F to 225°F (-40°C to 107°C). These features make it suitable for industrial machinery, manufacturing equipment, pumps, reducers, conveyors, and electric motors under normal operating conditions.
