Oil seals can be found in driveshafts, crankshafts, and hydraulic cylinders, where they help lubricate a rotating shaft using oil or grease. Typically, they are made of metal encased in rubber, supported by a garter spring on the inner lip.
What is the difference between single and double lips? Double-lipped rotary seals provide additional protection against contaminants like dust and dirt.
What is the best size? For precise sizing, consult our Oil Seal Tolerance Guide. Generally, oil seals require a tight tolerance between the outer diameter and housing. The garter spring, however, allows for a slightly larger tolerance to help reduce friction with the rotating shaft.
