Types of O-Rings
O-rings are categorized based on their application and the presence of movement.
| Type | Description | Applications | Advantages | Disadvantages |
|---|---|---|---|---|
| Static | Used in stationary applications where there is no relative motion between surfaces. | Gaskets, seals in non-moving parts | Simple design, easy to install, cost-effective | Limited resistance to wear and tear, not suitable for dynamic applications. |
| Dynamic | Used in applications involving movement (reciprocating, rotating, or oscillating). | Piston seals, rod seals, rotary shaft seals | Withstands movement, good sealing in dynamic conditions | More complex design, higher friction, potential for premature wear. |
| Microminiature | Extremely small O-rings with inner diameters less than 1 mm. | Apple Watch components, microfluidic devices | Suitable for miniature applications | Difficult to manufacture and handle. |
| Macrominiature | Extremely large O-rings with large inner diameters. | Specialized industrial applications | Suitable for large-scale sealing applications | Difficult to manufacture and handle. |
