The Timken Company 412871 Radial Shaft Oil Seal

The Timken National 412871 radial shaft oil seal (Seal Type 41, Series 410000) delivers dependable lubricant retention and protection against dust, dirt, and moisture in industrial rotating equipment. With a dual-lip nitrile construction and a spring, it seals a 2.625 in (66.675 mm) shaft, fits a 3.355 in (85.217 mm) outside diameter, a 3.350 in (85.090 mm) housing bore, and has an overall width of 0.375 in (9.525 mm). The steel-case with inner-case design, Redi-Coat finish, supports up to 3000 ft/min shaft surface speed and operates from -40°F to 225°F (-40°C to 107°C). Commonly used in gearboxes, pumps, electric motors, conveyors, and compressors for preventive maintenance and seal replacement to minimize lubricant leakage and extend bearing service life; compatible replacements include SKF 412871, CR 412871, and National 412871.
