hydraulic cylinder seal replacement

The design of the lip is crucial; its profile allows it to make optimal contact with the shaft, creating a seal that can accommodate the shaft's rotation. Some rotary lip seals also include a dust lip or exclusion barrier, which helps protect the primary sealing lip from contaminants such as dirt and debris.

One of the primary characteristics of high temperature oil seals is their ability to maintain flexibility and resilience at elevated temperatures. Traditional rubber seals may become brittle and lose their sealing capabilities when exposed to heat. In contrast, high temperature oil seals retain their mechanical properties, ensuring that they continue to perform their sealing function effectively even in harsh conditions. Typically, these seals can withstand temperatures ranging from 150°C to over 300°C, depending on the specific material used.

The design of high-pressure rotary shaft seals typically includes a flexible sealing lip that makes contact with the rotating shaft, combined with a robust outer component that holds the seal in position. The materials used in these seals must be durable and resistant to wear, heat, and chemicals. Common materials include elastomers like nitrile rubber, fluorocarbon rubber, and special composites designed for high-performance situations.
