Cross section of an R25 / VC style oil seal. This is a spring less design single sealing lip seal arrangement.
An R25 / VC oil seal consists of two basic components: The Sealing Element (the nitrile rubber part), the Metal Case. 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 gasoline. Operation temperatures are recommended from -40deg C to 120deg C. It also functions well under dry environment, but only for intermittent periods.
Construction
The seal cases are made from SAE 1008-1010 Carbon Steel.
The principle function of the metal case is to impart rigidity and strength to the seal.
