The Timken Company 416125 Radial Shaft Oil Seal

The Timken National 416125 radial shaft oil seal provides dependable lubricant retention and contamination protection in heavy-duty industrial gearboxes, pumps, electric motors, conveyors, and compressors where a rugged shaft seal is required. This Type 41 multi-lip seal features a steel case with an inner case, a nitrile (NBR) lip set with a spring, and Redi-Coat for easy installation. It fits a 3.625 in (92.075 mm) shaft, has an outside diameter of 5.004 in (127.102 mm), a housing bore of 4.999 in (126.975 mm), and an overall width of 0.500 in (12.700 mm). The seal supports up to 3000 ft/min shaft surface speed and tolerates misalignment of 0.015 in at 800 rpm or 0.010 in at 4200 rpm. It is rated for operating temperatures from -40°F to 225°F (-40°C to 107°C). Common replacements include SKF 416125, CR 416125, and National 416125, reflecting broad compatibility with standard industrial sealing programs. Use this seal for preventive maintenance, equipment repair, and seal replacement to minimize lubricant leakage and extend bearing life.
