"DNC cylinders" typically refer to pneumatic cylinders that follow the ISO 15552 standard, also known as DNC (ISO 15552) cylinders. Here are the main features of DNC cylinders:
1. **ISO 15552 Standard:** DNC cylinders adhere to the ISO 15552 standard, which specifies the design and dimensions for pneumatic cylinders. This standard ensures interchangeability and compatibility across different manufacturers.
2. **Bore Size:** DNC cylinders come in various bore sizes, which represent the diameter of the cylinder. Common bore sizes are specified in the ISO 15552 standard, allowing users to choose the appropriate size for their application.
3. **Double-Acting Operation:** Most DNC cylinders are double-acting, meaning they have two ports for air supply, allowing for both extension and retraction of the piston rod. This provides better control and flexibility in applications.
4. **Magnetic Piston:** Many DNC cylinders have a magnetic piston, which allows for the easy installation of position sensors. Magnetic pistons enable accurate and reliable sensing of the piston position.
5. **Adjustable Cushioning:** DNC cylinders often feature adjustable cushioning at both ends. Cushioning helps to reduce impact forces at the end of stroke positions, enhancing the cylinder's performance and extending its lifespan.
6. **Aluminum Construction:** DNC cylinders are commonly constructed from aluminum, providing a lightweight and durable solution. Aluminum construction also offers resistance to corrosion, making these cylinders suitable for various environments.
7. **Mounting Options:** DNC cylinders typically have standardized mounting options, allowing easy installation and integration into different systems. Mounting accessories and brackets are designed to be compatible with the ISO 15552 standard.
8. **Seals and Lubrication:** High-quality seals are used in DNC cylinders to ensure reliable and leak-free operation. Lubrication options may vary, and some cylinders are designed to operate without the need for additional lubrication.
9. **Wide Range of Applications:** DNC cylinders are versatile and find applications in various industries, including manufacturing, automation, packaging, and more. Their standardized design makes them suitable for integration into different pneumatic systems.
10. **Identification Marks:** DNC cylinders often have identification marks, such as part numbers and compliance with the ISO 15552 standard, to assist users in selecting the right cylinder for their needs.
