The Timken Company 417211 Radial Shaft Oil Seal

The Timken 417211 radial shaft oil seal is a nitrile (NBR) lip-seal with a spring-loaded Type 41 multi-lip design in Timken’s Series 410000, engineered to retain lubricants and exclude contaminants from rotating equipment. It uses a steel case with inner case and fits a 3.875 in (98.425 mm) shaft and a 4.881 in (123.977 mm) outside diameter, with a housing bore of 4.875 in (123.825 mm) and an overall width of 0.500 in (12.700 mm). Redi-Coat is included. The seal is rated for a maximum shaft surface speed of 3000 ft/min and a operating pressure of 7 psi, and it accommodates temperatures from -40°F to 225°F (-40°C to 107°C). Common replacements include SKF 38717, CR 417211, and National 417211. Applications span general-purpose industrial shaft sealing in gearboxes, pumps, conveyors, reducers, electric motors, compressors, and other power-transmission equipment requiring reliable sealing.
