Polytetrafluoro-ethylene (PTFE - Teflon)
- In conclusion, the humble square rubber gasket, though often overlooked, is a vital element in various industries. Its durability, adaptability, and sealing capabilities make it an essential component in maintaining the functionality and efficiency of countless systems. Whether it's keeping our cars running smoothly, our homes free from leaks, or our medications safe from contamination, the role of the square rubber gasket cannot be overstated. It is a testament to the power of engineering and the importance of even the smallest parts in our complex world.
- 3. Material Preparation The selected material is then prepared by mixing it with additives and curing agents, if necessary.
It is wedge-shaped to be pressed against the shaft surface and makes contact with the shaft to ensure sufficient sealing performance and suitability for operation at high peripheral speed.
Types of oil seals include:
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.
Among the most common causes of oil seal failure are:
Power steering oil seals are integral to the functionality of the vehicle's power steering system. These seals are responsible for containing the hydraulic fluid within the power steering mechanism, preventing leaks and maintaining the smooth operation of the steering components. Power steering oil seals contribute to the proper functioning and longevity of the steering system, ensuring precise and responsive vehicle control.
Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.
Oil seals are integral components in a range of machinery and equipment, playing a vital role in keeping lubricants in, contaminants out, and machinery operating efficiently. Understanding the design, materials, and selection factors of oil seals can help you make an informed choice regarding your industrial needs. The reliability, longevity, and efficiency the right oil seal can bring to your machinery is priceless.
