Drive Shaft Seals

Drive shaft Oil seals are generally used for dealing lubricating oil, diesel, grease and any other fluids, powders, gasses or granular solids. For trouble -free operation and optimal service life, drive shaft seals must seal and survive. Both proper design and material choice are critical if they are to seal against penetrating dust and dirt, and to prevent any liquids etc escaping. Good oil seal design is therefore, a balance between optimum running properties of the material, lip design and integral garter spring.

Drive shaft seals come in many shapes and sizes with single lip, double lip and wiper lip, depending on where it is fitted in the engine. The sealing capacity of an oil seal depends on the pressure exerted by the sealing lip on the shaft. The degree of pressure is directly related to the pre-stress and dimensional tolerances of the seal and the shaft.

Drive shaft seals now tend to be made out of Viton (Dupont Trademark) with a temperature resistance range from -40°C to approximately 200°C
