Although there are many styles of Oil Seals, they all generally consist of a flexible rubber lip bonded to a rigid metal case. Most also contain a third element – a garter spring –fitted the rubber lip to provide additional sealing force, both initially and over the life of the seal. The total radial force of the sealing lip is a function of the rubber pre-tension, coupled with the tensile spring force. The sealing lip may be lathe cut or ready molded, and may feature molded-in hydrodynamic aids to assist sealing in demanding applications. The metal case may be exposed or have rubber molded around it for ease of assembly or improved static sealing.

SHAFTS SPEEDS AND LIP MATERIALS
MATERIAL
FKM Temperature application range: -25 to +250 °C.FKM is a copolymer made of highly fluorinated hydrocarbons and developed during the 1950s. FKM seals display very good resistance to media, ozone and aging. The material is also stable in fuels as well as petroleum-based oils and greases, along with aliphatic and aromatic hydrocarbons.Its very good resistance to aging and ozone as well as its very low gas permeability (good suitability for vacuum applications) and its high thermal resistance make FKM attractive for various applications in the general industry. FKM is resistant to most special lubricants and chemicals which are not suitable for other materials such as ACM, NBR and HNBR. FKM is used wherever high demands are placed on chemical resistance high temperatures and high speeds occur, such as with radial shaft seals for pumps and gears as well as in various general industry applications.
NBR Temperature application range: -25 to +100 °C.It is one of the most important sealing materials in the mechanical engineering sector, is used in both static and dynamic applications and features low gas permeability. NBR has good resistance to oils, greases, silicones, hydraulic fluids and aliphatic hydrocarbons. At room temperature, NBR also offers good resistance to diluted acids and alkalis. It has good abrasion resistance and offers high elasticity for use under high mechanical forces. The very good recovery behavior deserves special mention. NBR is used in general industry applications like gears, pumps and industrial machinery.
The WDH product brand portfolio offers very high availability of dimensions and variants of radial shaft seals from stock. In addition, customer-specific developments are possible.
