Skeleton Oil Seals
Rubber oil seals designed to withstand high pressure, temperature and wear for sealing applications in various industries
Skeleton oil seals are specialized sealing components designed for high-pressure and high-temperature applications. With over 30 years of experience in rubber manufacturing, Saiensi continually innovates and refines its technology to produce skeleton oil seals with reliable resistance to temperature, pressure, and wear. Saiensi’s expertise in material formulation and manufacturing processes ensures stable performance, and proficiency in fabric-reinforced oil seal design allows the compony to respond quickly to customer customization requirements.
- High strength and pressure resistance: Can withstand pressures up to 50MPa, ensuring stable operation of hydraulic systems and machinery.
- Wide temperature adaptability: Operating range from -40℃ to 200℃, customizable based on material, suitable for extreme environments.
- Works well with various fluids: Compatible with mineral oil, water, ethylene glycol, and other working media.
- Wear-resistant and durable: Internal fabric reinforcement strengthens the sealing structure, reducing replacement frequency and maintenance costs.
- Customization capability: Material, dimensions, and structure can be optimized based on specific conditions such as oil pressure, rotational speed, and temperature variation.
- Technical support: Seal analysis, fatigue testing, and selection guidance are provided to reduce downtime risks.
