Inch - Bore:5.251, Shaft:4.25, Width:0.375 Oil & Grease Seal

Oil seals are used to seal around a rotating shaft and keep an oil-based lubricant inside an axle or housing. Grease seals are used to seal more viscous grease lubricants in a variety of rotary shaft applications. Styles with double lips, enhanced lip compound materials, and/or a spring on one of the lips increase the effectiveness of the oil or grease seal in extreme environments - keeping contaminants out and lubrication in. Other sizes, lip compounds and/or case materials are available on request for quote.
