Shaft OD X Bore ID X Seal Width - Type SC Metric Oil Seal

Nitrile Rubber Single Lip R21 / SC Oil Seals

An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts. This is mainly achieved by the sealing element. Nitrile Rubber (NBR)
NBR is the most commonly used seal material. It has good heat resistance properties, good resistance to oils, salt solutions, hydraulic oils, and petrol, diesel and other gasoline products. Operation temperatures are recommended from -40deg C to 120deg C. It also functions well under dry environment, but only for intermittent periods.
	Cross section of an R21 / SC style oil seal. This is a single sealing lip seal arrangement.
Construction The seal cases are made from SAE 1008-1010 Carbon Steel and are often coated in a very thin layer of Nitrile rubber to assist sealing in the housing. The principle function of the metal case is to impart rigidity and strength to the seal.
The spring is made from SAE 1050-1095 Carbon Spring Steel which has a protective zinc coating. The principle function of the spring is to maintain an even gripping pressure around the shaft
