The Timken Company 453182 Oil Seal

The Timken National Oil Seal 453182 is a 3.000 in shaft-diameter, 4.004 in outer diameter single-lip oil seal designed to retain lubricants and exclude dirt, moisture, and other contaminants from rotating shaft systems. Built with a solid inner-case construction and nitrile (NBR) lip material, this Type 45 seal (Series 450000) features a single lip with spring and is Redi-Coat ready, enabling quick surface protection. It fits an ID of 3.000 in (76.20 mm), an OD of 4.004 in (101.70 mm), and a housing bore of 3.999 in (101.57 mm), with a width of 0.437 in (11.10 mm). The seal operates in continuous temperatures from -40°F to 225°F (-40°C to 107°C) and supports a maximum shaft surface speed of 3000 ft/min, with misalignment tolerances of 0.015 in at 800 rpm and 0.010 in at 4200 rpm. Commonly used in industrial gearboxes, pumps, electric motors, conveyor systems, construction equipment, mining machinery, and heavy-duty vehicle drivetrains to reduce lubricant leakage and prevent contaminant ingress.
