The Timken Company 5168 Radial Shaft Oil Seal

The Timken National Oil Seal 5168 is a multi-lip, spring-loaded radial shaft oil seal kit designed to retain lubricants while preventing dirt, moisture, and other contaminants from entering rotating shaft systems. It uses an inch-based nitrile rubber (NBR) sealing element in a steel case (Redi-Coat: Yes) and has a shaft ID of 1.062 in, an outside diameter of 2.129 in, a housing bore of 2.125 in, and an overall width of 0.625 in, weighing about 0.17 lb. This 5168 seal is part of the Timken National 5000 Series, with a Type 41 multi-lip with spring construction, and is commonly used in industrial gearboxes, electric motors, pumps, compressors, conveyors, and agricultural equipment for general-purpose rotary sealing in oil- and grease-lubricated equipment. Common replacements include SKF Equivalent Oil Seal, CR (Chicago Rawhide) Equivalent Oil Seal, and National 5000 Series Oil Seal Kit.
