The Timken Company 416557 Radial Shaft Oil Seal

The Timken Company 416557 Radial Shaft Oil Seal is a Type 41 multi-lip nitrile radial shaft seal designed to retain lubricant and prevent contaminants from entering bearing assemblies in heavy-duty rotating equipment. It is a Timken National Series 410000 industrial seal with a multi-lip with spring configuration and nitrile (NBR) lip material, housed in a steel case with inner case and finished with Redi-Coat. Key dimensions include a shaft diameter of 5.125 in (130.175 mm), an outside diameter of 6.131 in (155.727 mm), a housing bore of 6.125 in (155.575 mm), and an overall width of 0.500 in (12.700 mm). The seal supports up to 3000 ft/min shaft speed and features misalignment tolerance of 0.015 in at 800 rpm and 0.010 in at 4200 rpm. The operating temperature range is -40°F to 225°F (-40°C to 107°C). Typical applications include industrial gearboxes, pumps, electric motors, conveyors, compressors, mining equipment, and other heavy-duty power transmission equipment where effective shaft sealing improves equipment reliability and reduces lubricant leakage. Common replacements include SKF 416557, CR 416557, and National 416557.
