Timken 486567 Oil Seal

The Timken National Oil Seal 486567 is a single-lip oil seal (with spring) designed to retain lubricants and block dirt, moisture, and other contaminants from entering rotating shaft systems. It belongs to Timken’s 480000 series and uses Nitrile (NBR) lip material in a solid construction for sealing in industrial gearboxes, pumps, electric motors, conveyor systems, manufacturing equipment, and general power transmission equipment. Key specifications include shaft diameter 3.375 in (85.725 mm); outside diameter 4.375 in (111.125 mm); housing bore 4.370 in (110.998 mm); overall width 0.250 in (6.350 mm); durometer 60–80; continuous operating temperature -40°F to 225°F (-40°C to 107°C); and weight 0.27 lb (0.12 kg). Typical applications involve rotating equipment where reliable shaft sealing is essential to protect bearings and lubricated components, with use in replacements, rebuilds, retrofits, and preventive maintenance; common replacements include SKF equivalent oil seal, CR (Chicago Rawhide) equivalent oil seal, and National 480000 series oil seal.
