Oil Seals
Oil seals / Rotary shaft seals / Radial shaft seals / Grease Seals are used to seal rotary applications such as a shaft or rotating bore. Many early designs would consist of a rubber sealing lip in conjunction with a stainless steel spring and are still used today for many applications. However, as sealing technology has advanced, the majority of modern day oil seals utilize an elastic sealing lip in conjunction with a stainless steel spring.
