Q&A
1. What is a rotary spring energized seal?
A rotary spring energized seal is a dynamic sealing device that uses a spring (typically V-shaped) to energize the sealing lip against a shaft or housing, ensuring leak-free performance even at low pressures and high speeds.
2. What materials are used in your S19-F seal?
Our S19-F seal features a PTFE (polytetrafluoroethylene) jacket and a stainless steel V-spring. PTFE offers excellent chemical resistance and low friction, while the spring provides consistent sealing force.
3. Can you manufacture seals based on my custom drawings?
Yes, we are a factory that specializes in custom manufacturing. Please send your drawings or specifications, and we will produce seals that meet your exact requirements.
4. What is the temperature range for these seals?
Our PTFE-based spring energized seals can operate in temperatures ranging from -200°C to +260°C, depending on the specific PTFE grade and spring material.
5. Are these seals suitable for high-speed rotary applications?
Yes, they are designed for rotary motion and can handle high shaft speeds. The low friction PTFE jacket minimizes heat generation and wear.
6. What industries commonly use these seals?
They are widely used in chemical processing, oil & gas, food & beverage, pharmaceutical, automotive, and general industrial machinery.
7. Do you offer samples before bulk orders?
Yes, we can provide samples for evaluation. Please contact our sales team to discuss sample requests and lead times.
8. What is the minimum order quantity (MOQ)?
Our MOQ is flexible. For standard sizes, we can accommodate small orders. For custom designs, MOQ may vary based on complexity and material availability.
