1. Product Overview

Silicone skeleton oil seal is a high-performance seal that combines the elasticity of silicone and the strength of metal skeleton. It is usually used in environments that require high temperature, high pressure, chemical corrosion and long life. It is widely used in hydraulic systems, automobiles, aerospace, food and pharmaceutical industries, etc., mainly used to prevent leakage of oil, gas or other fluids.

2. Working principle

Sealing effect: Silicone skeleton oil seal consists of silicone sealing lip, metal skeleton and spring. The metal skeleton provides mechanical strength and support, and the silicone sealing lip forms a close contact with the contact surface to prevent liquid or gas leakage. The spring applies constant pressure on the sealing lip to ensure sealing performance.

Elasticity and stability: The elasticity of silicone enables the oil seal to adapt to changes such as vibration and axial movement of moving parts to maintain the sealing effect. The metal skeleton provides stable structural support, making it suitable for high pressure and complex environments.

3. Application fields

Automotive industry: widely used in automobile engines, gearboxes, oil seals, steering systems and other components to prevent leakage of lubricating oil, fuel and coolant.

Hydraulic system: Applicable to hydraulic pumps, hydraulic cylinders, hydraulic motors and other equipment to prevent liquid leakage and protect the system from contamination.

Aerospace: Used in hydraulic and fuel systems of spacecraft, aircraft engines and equipment to ensure the reliability of equipment under high temperature and high pressure.

Chemical and petroleum industry: Used in chemical equipment, oil drilling, pipeline sealing, etc. to prevent chemical leakage and protect equipment from corrosion.

Food and medical industry: Due to its biocompatibility and non-toxic properties, silicone skeleton oil seals are widely used in food processing, pharmaceutical equipment and medical equipment for sealing needs.

4. Material selection

Metal skeleton: Metal skeletons are often made of stainless steel or high-strength alloy materials, providing strong structural support and able to withstand high-pressure working environments.

Spring: The internal spring is generally made of stainless steel or carbon steel to ensure that the spring force is continuously effective during the working process.

5. Size and customization

Standard size: Silicone skeleton oil seals can provide standard sizes according to the size requirements of the equipment. Common oil seal diameters range from a few millimeters to hundreds of millimeters, and the thickness can be selected according to the working pressure and sealing requirements.

Customization options: The size, hardness, sealing lip shape, skeleton structure, etc. of the oil seal can be customized according to the specific application to meet the sealing requirements in special working environments.

6. Installation and maintenance

Installation method: When installing the silicone skeleton oil seal, it is necessary to ensure that the installation surface is clean and smooth to avoid contaminants affecting the sealing performance. Avoid excessive stretching or twisting of the oil seal during installation to ensure that it is properly installed in the equipment.

Maintenance and inspection: Check the status of the oil seal regularly to ensure that there is no leakage. If the sealing lip is worn, cracked or aged, it should be replaced in time.

7. Advantages

High temperature and chemical corrosion resistance: Silicone skeleton oil seals can provide long-term and stable sealing effects in extremely high temperature and corrosive environments.

Biocompatibility and non-toxicity: Suitable for food, medical and environmental protection industries.

High mechanical strength and stability: The metal skeleton provides structural support to ensure that excellent sealing effects are maintained under high pressure.

Long life: Due to its wear and aging resistance, silicone skeleton oil seals have a long service life, reducing the maintenance and replacement frequency of equipment.

8. Disadvantages

Higher cost: Compared with ordinary rubber oil seals, silicone skeleton oil seals have higher costs, but due to their special high temperature resistance and chemical resistance, they are usually used in high-end equipment or high-demand application environments.

High requirements for the installation environment: During installation, it is necessary to ensure cleanliness and no impurities to ensure the sealing effect.
