Technical Features of Hydraulic O-Rings
The performance of a hydraulic O-ring is significantly impacted by its material properties and design. Material selection is crucial, considering factors like operating temperature, pressure, and the type of hydraulic fluid used. Common materials include Nitrile (NBR), Fluorocarbon (FKM/Viton), Silicone (VMQ), and EPDM. NOK-CN Seals, for example, offers O-rings in a wide array of materials to cater to diverse applications. The O-ring’s cross-sectional shape and size also play a critical role in its sealing effectiveness.
| Feature | Description |
|---|---|
| Material | NBR, FKM, Silicone, EPDM, HNBR, FVMQ, FFKM; choice depends on chemical compatibility, temperature resistance, and pressure requirements. |
| Hardness (Shore A) | Measures the material’s resistance to indentation; influences the seal’s compression and ability to withstand pressure. |
| Size (ID, OD) | Inner and outer diameters determine the O-ring’s fit within the groove; precision sizing is essential for effective sealing. |
| Cross-section | Round is the standard; other shapes like square or rectangular are used for specific applications. |
| Surface Finish | Smooth surfaces minimize friction and wear; imperfections can lead to leaks. |
