Furthermore, lithopone is known for its resistance to heat and chemicals, making it an ideal additive for plastics that will be used in demanding conditions
Oil seals are available in an immense range of sizes, for shafts from a few millimetres to several metres. Once the shaft diameter, groove diameter (housing diameter) and groove width are known, selecting an appropriate oil seal is a simple task. An oil seal or its product description is usually associated with three dimensions, for example 6x15x4. These refer to the sizes of the hardware for which the oil seal is designed. In this example, this oil seal is suitable for: 6-mm shaft diameter x 15-mm groove diameter x 4-mm minimum groove width.

(5) The surface finish of the shaft directly affects the service life of the oil seal, that is, the higher the shaft finish, the longer the service life of the oil seal.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
- One of the key advantages of synthetic rubber gaskets is their versatility. They can be custom-made to fit any shape or size, ensuring a perfect seal every time. This flexibility makes them suitable for use in a variety of industries, from automotive to aerospace, where they are used in engines, pumps, valves, and other equipment that requires a dependable sealing solution.
