7. Test the System After reinstallation, it’s crucial to test the system under operational conditions. Check for leaks and ensure the cylinder is functioning as expected.

2. Aerospace In aerospace applications, oil seals are essential for maintaining the integrity of hydraulic systems and preventing contamination that could lead to system failures. The high-performance materials used in oil seals are designed to withstand the extreme conditions encountered in flight.

Seals in hydraulic cylinders serve multiple purposes. They prevent hydraulic fluid from leaking out of the cylinder, protect against contaminants entering the system, and maintain pressure within the cylinder. Common seal types include O-rings, piston seals, rod seals, and backup rings, each designed for specific functions and pressure conditions. The integrity of these seals is crucial for the hydraulic system's performance, efficiency, and longevity.

1. Leak Prevention The most significant function of oil seals is to prevent the leakage of lubrication fluids from within a mechanical system. Oil leaks can lead to reduced lubrication, resulting in increased friction, overheating, and ultimately premature wear or failure of components.

The 40% - 80% - 10% principle is often used to describe the ideal distribution of life expectancy, performance, and operational efficiency when considering oil seals. Here’s a breakdown of what each percentage signifies

The 20x35x7 oil seal is widely used across several sectors, including automotive, industrial machinery, and aerospace. In automotive applications, it is commonly found in various components, such as engines, transmissions, and differentials. For instance, it effectively seals crankshafts and camshafts, ensuring that lubricants do not leak and that contaminants cannot enter the engine.
