Timken 455260 Oil Seal

Timken National Oil Seal 455260 is a single-lip oil seal designed to retain lubricants and prevent dirt, moisture, and other contaminants from entering rotating shaft systems. It belongs to the National 450000 series and uses a nitrile (NBR) lip in a solid-with-inner-case construction with Redi-Coat for easier installation. Key dimensions are shaft ID 2.062 in (52.375 mm), outside diameter 3.628 in (92.151 mm), housing bore 3.623 in (92.024 mm), and width 0.468 in (11.887 mm); it supports up to 3000 ft/min shaft surface speed. The seal operates from -40°F to 225°F (-40°C to 107°C) and has misalignment tolerances of 0.015 in at 800 rpm and 0.010 in at 4200 rpm. Typical applications include industrial gearboxes, pumps, electric motors, conveyor systems, mining equipment, construction machinery, and other general-purpose rotating equipment requiring reliable lubrication containment and contaminant exclusion.
