The Timken Company 472258V Oil Seal

The Timken National Oil Seal 472258V is a double-lip with spring oil seal that uses a fluoroelastomer (FKM/Viton) sealing lip for high-temperature lubricant retention and contaminant exclusion in rotating shaft systems. It features a steel case without inner case and Redi-Coat, with an inch-based size: shaft ID 1.375 in (34.925 mm), outside diameter 2.004 in (50.902 mm), housing bore 2.000 in (50.800 mm), and overall width 0.312 in (7.925 mm); maximum shaft surface speed is 3000 ft/min and misalignment tolerance is 0.015 in at 800 rpm or 0.010 in at 4200 rpm. Designed for continuous operation from -40°F to 400°F (-40°C to 204°C) with a durometer of 75–85, it serves general purpose rotating equipment, chemical processing equipment, and high-temperature power transmission systems in industrial gearboxes, pumps, electric motors, and conveyors, with common replacements including SKF equivalent FKM oil seal, CR equivalent, and National 470000 series Viton oil seal.
