Precision mold: rotating shaft lip seal

Rotating shaft lip seals are often referred to as oil seals. The oil seal seals the lubricating oil or other medium by contacting the shaft with rubber or the like to achieve the sealing effect.

Initially, the oil seal was made of leather. Due to the development of synthetic rubber after World War II, the oil seal production process was improved, and rubber was used instead of the original leather. The amount of oil seals is also gradually increasing.

Especially with the industrial development of various countries, the improvement of the level of machinery manufacturing, the research and development of aerospace and the development of the automobile industry, the demand for oil seals is increasing, and the quality requirements for oil seals are getting higher and higher.

High requirements and high dosage require oil seals to be used in harsher environments.

Through extensive research and development of oil seal materials, performance tests, structural analysis and other extensive research. The oil seal has excellent performances such as high and low temperature resistance, high and low pressure resistance, wear resistance, various media resistance and high speed motion.
