Timken National 473453 Oil Seal

The Timken National 473453 Oil Seal is a double-lip, spring-loaded shaft seal (Series 470000, Design Type 47) engineered to retain lubricant while preventing dirt, moisture, and other contaminants from entering rotating shaft systems in demanding industrial environments. It uses Nitrile (NBR) lip material and a solid construction without an inner case, with Redi-Coat protection, and is sized for an inch-based measurement system. Key dimensions include a shaft bore of 1.844 in (46.84 mm) inner diameter, an outside diameter of 2.879 in (73.13 mm), a housing bore of 2.875 in (73.03 mm), and an overall width of 0.375 in (9.525 mm); maximum shaft surface speed is 3000 ft/min, and misalignment tolerance is 0.015 in at 800 rpm and 0.010 in at 4200 rpm. Operating temperature ranges from -40°F to 225°F (-40°C to 107°C), and the seal weighs 0.13 lb (0.06 kg). Typical applications span general power transmission and rotating equipment such as industrial gearboxes, pumps, electric motors, conveyors, manufacturing equipment, and agricultural machinery, where reliable sealing protects bearings and lubricated components. Manufacturer part number 473453, Timken brand National, Product Type Oil Seal, with a solid design and compatibility reflected in common replacements like SKF equivalent oil seals, CR (Chicago Rawhide) equivalents, and the National 470000 series oil seal.
