Timken 455009 Oil Seal

The Timken National Oil Seal 455009 is a single-lip oil seal designed to retain lubricants and keep dirt, moisture, and other contaminants from entering rotating shaft systems. It features a loaded spring, Type 45 design, and nitrile (NBR) construction for demanding environments, with a shaft ID of 2.750 in, an outside diameter of 3.881 in, a width of 0.468 in, durometer 60–80, and a continuous operating temperature range of -40°F to 225°F (-40°C to 107°C). This National 450000 Series seal from Timken is commonly installed in industrial gearboxes, pumps, electric motors, conveyor systems, and heavy-duty power transmission equipment to protect bearings and lubricated components and reduce lubricant leakage and contaminant ingress. Common replacements include SKF 27470, Chicago Rawhide (CR) equivalent oil seals, and National 450000 Series oil seals.
