- In the aerospace industry, rubber edge gaskets are used in aircraft engines, hydraulic systems, and avionics equipment to seal critical components and protect them from external contaminants. Their high temperature resistance and chemical compatibility make them suitable for use in demanding aerospace applications

- Seal Cocking: Misalignment during installation can cause one side of the sealing lip to have greater shaft interference leading to uneven wear or leakage. Using properly sized installation tools is crucial for prevention.
Prepare the shaft and prevent damage
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.
The pulley is kept from turning on the crankshaft by a key fitting into grooves on the crankshaft and pulley.

Proper maintenance and regular inspection are vital for prolonging the service life of oil seals and preventing unplanned downtime. Here are some tips:
