The Timken Company 410102 Radial Shaft Oil Seal

The Timken National 410102 radial shaft oil seal is a double-lip, spring‑loaded nitrile (NBR) seal designed to retain lubricant and block dust, dirt, and moisture from entering bearing assemblies in industrial gearboxes, pumps, electric motors, conveyors, compressors, and other rotating equipment. Part of Timken’s 410000 series (Type 41), it uses a steel case with inner case and Redi-Coat finish for durable installation. Key dimensions are a 2.000 in shaft diameter, 3.376 in outside diameter, 3.371 in housing bore, and 0.469 in overall width. It is rated for a maximum shaft surface speed of 3000 ft/min and an operating temperature range from −40°F to 225°F (−40°C to 107°C). This seal supports general-purpose industrial sealing needs where reliable lubricant retention and protection against contaminants are required, with common replacements including SKF 410102, CR 410102, and National 410102.
