A typical hydraulic ram seal kit includes O-rings, piston seals, cylinder seals, wipers, and backup rings. Each component plays a specific role
4. Home Appliances Even in everyday appliances like washing machines and refrigerators, oil seals are critical to offering smooth operation and preventing leaks. The 14x22x5 dimensions can suit specific models where space constraints exist.
2. Decreased Performance If machinery is struggling to maintain pressure or perform at its usual efficiency, the seals may be compromised. Reduced power and responsiveness are often linked to worn seals.
5. Marine Applications Seals are significant in preventing water ingress and maintaining the integrity of various components in marine vessels.
3. V-Rings These seals feature a flexible, v-shaped lip that makes contact with the shaft. They can be used in tandem with other sealing devices to enhance sealing performance.
2. PTFE Seals Known for their high resistance to heat and chemicals, PTFE seals are suitable for more demanding environments. Although more expensive, they can significantly reduce friction and wear within hydraulic systems.
4. Versatility Dust lip seals are available in a wide range of sizes and materials, making them suitable for various applications. They can be found in automotive, aerospace, industrial machinery, and household appliances, among others.
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
An oil seal is designed to perform three major functions: to prevent lubricants from leaking outside the seal even under high pressure, to act as a barrier to retain the lubricating oil, and to prevent dirt and other contaminants from entering the unit.
