4. Zlepšení bezpečnosti Automatizace snižuje riziko úrazů při manipulaci s těžkými břemeny a zvyšuje osvětlení a viditelnost v pracovním prostoru.
Finally, consider the size and shape of the gasket, as well as any specific design requirements that may impact the gasket's performance. Custom-made natural rubber gaskets can be designed to meet the unique needs of your application, ensuring a precise fit and optimal sealing performance.
In these instances, Viton can be the perfect sealing material for methanol/ethanol-blended gasoline.
3. The spring on the lip of the oil seal tends to provide support to the lip and prevents the lubricant from leaking outside and also prevents the entry of contaminants from outside.
Modern engine concepts, like higher engine speeds and oil temperatures, longer intervals between oil changes and lubricants with modern additives, require new solutions for dynamic seals. They have to withstand the high loads lastingly. PTFE technology is the answer, since it perfectly meets these demands.

Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
Oil seals are called rotary shaft seal or radial lip also.

a)
Why is mechanical seal important in this situation? It is because the rotating shaft has to move in a wet environment, but there should not be the leakage of pressurized fluid. Hence, the role of a seal is quite critical.

Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
Another critical factor to consider is the type of seal most suitable for particular machinery. When selecting your mechanical sealing solution, assess your machine’s shaft speed, temperature, pressure, environment, and the medium coming into contact with the seal during an operation. These factors help determine the color, size, sealing element, lip material to choose from, and if it can be sealed out or sealed in.
