The Timken Company 417549 Radial Shaft Oil Seal

The Timken National 417549 radial shaft oil seal is a Type 41, multi-lip, spring-loaded seal engineered to retain lubricants and prevent contaminants from entering rotating equipment such as industrial gearboxes, pumps, electric motors, conveyors, and compressors. It uses a steel case with inner case, nitrile (NBR) sealing lip, and Redi-Coat construction for general-purpose industrial shaft sealing (Series 410000). The seal accommodates a 5.250 in (133.350 mm) shaft, a 6.757 in (171.628 mm) outside diameter, a 6.750 in (171.450 mm) housing bore, and an overall width of 0.500 in (12.700 mm). Lip configuration is multi-lip with spring, lip material nitrile, and maximum shaft speed rated at 3000 ft/min. Misalignment tolerance is 0.015 in at 800 rpm and 0.010 in at 4200 rpm, with a 7 psi pressure rating and an operating temperature range of -40°F to 225°F (-40°C to 107°C). Common replacements include SKF 417549, CR 417549, and National 417549.
