Oil Seal

Oil seals, also known as shaft seals, are radial lip type seals which are primarily used for retaining lubricants in equipment having rotating, reciprocating or oscillating shafts. The rotating shaft application is most common.

An oil seal normally consists of three basic components: the rubber sealing element, the metal case and the garter spring. The purpose of the sealing element is to stop the fluid from leaking between the shaft and housing. The metal case will give rigidity and strength to the seal while it is being held in the bore or recessed groove. The garter spring maintains the radial force exerted by the sealing lip around the shaft surface.

Oil seals or shaft seals are an integral part in any rotating and moving part assembly. Oil seals find great deal of usage in gearboxes, hydraulic cylinders, etc.

OS5200 Oil seal NBR/steel

NBR rubber is the most widely used elastomer in most current applications. It is particularly recommended in case of contact with paraffin-based (aliphatic) oils, mineral oils and fats (oils for engines, gearboxes, differentials, etc.), hydraulic oils, water and aqueous solutions (lyes).

Suggested temperature range: -25°C to +100°C.

OS5700 Oil seal FKM/steel

FKM rubber has exceptional heat and chemical resistance. Its properties remain indefinitely stable up to about 200°C. It offers excellent performances in contact with aliphatic hydrocarbons, aromatic hydrocarbons (toluene, benzene, xylene), vegetable and mineral oils and fats, chlorinated solvents, ozone, light and atmospheric agents.

Suggested temperature range: -25°C to +200°C.
