Description: Rotary shaft seals, also known as radial shaft seals or just simply oil seals are used to seal rotary applications such as a shaft or rotating bore. Early designs utilised a leather sealing lip in conjunction with a garter spring and are still used today for some applications. However, the majority of modern day rotary shaft seals utilise an elastomeric sealing lip in conjunction with a garter spring. Many different designs are availabe featuring either rubber covered or metal cased outside diameters with a variety of lip designs incorporating wiper lips or hydrodynamic features to improve the sealing performance.

Applications: Rotary shaft seals are used throughout automotive, power transmission and general industry in many diverse applications. Wherever a bearing is used there will normally be a rotary shaft seal of some type to seal the bearing and prevent the ingress of dirt and water. 

Dichtomatik: Dichtomatik are able to supply rotary shaft seals in a vast range of seal designs and profiles to suit all applications. As well as traditionally used imperial dimensions, rotary shaft seals are available in all the dimensions covered in the DIN 3760/ DIN 3761 international standards. A brochure is available on request.
