PTFE balls are versatile components used in various industries due to their unique properties like chemical resistance, low friction, and high-temperature tolerance. They come in a wide size range, typically from 3mm (or 1/8 inch) up to 100mm (or 8 inches), with some suppliers offering custom-made sizes for large orders. The tolerance levels vary depending on the ball's diameter, ensuring precision for specific applications. Available in Virgin and Ultra-Modified grades, these balls cater to diverse needs, from industrial machinery to specialized equipment.
Key Points Explained:
-
Size Range of PTFE Balls
- PTFE balls are available in diameters ranging from 3mm (0.118 inches) to 100mm (3.937 inches). Some suppliers extend this range up to 8 inches (203.2mm) for custom orders.
- Smaller sizes (e.g., 1/8 inch or 3mm) are common for precision applications, while larger diameters suit heavy-duty or industrial uses.
- Stock availability varies, but manufacturers often accommodate bulk or made-to-order requests for non-standard sizes.
-
Tolerance Specifications
- Tolerance depends on the ball's diameter:
- Larger balls (e.g., >1 inch): Tolerance of ±0.005 inches with a maximum TIR (Total Indicator Reading) of 0.0005 inches.
- Smaller balls (e.g., <1 inch): Tolerance of ±0.003 inches and a TIR of 0.003 inches.
- Standard diameter tolerance is typically ±5%, but precision tolerances can be specified per requirement.
- Tolerance depends on the ball's diameter:
-
Material Grades
- Virgin PTFE: Pure form, ideal for applications requiring uncompromised chemical resistance and electrical insulation.
- Ultra-Modified PTFE: Enhanced with fillers (e.g., glass or carbon) for improved wear resistance, stiffness, or thermal conductivity.
-
Key Properties Driving Size Selection
- Chemical Resistance: Suitable for corrosive environments, regardless of size.
- Low Friction: Smaller balls are often used in valves or bearings, while larger ones may serve in conveyor systems.
- Temperature Resistance: Stable across sizes, withstanding extremes from -200°C to +260°C.
-
Applications by Size
- 3mm–20mm: Precision instruments, medical devices, or small bearings.
- 20mm–100mm: Industrial pumps, large-scale machinery, or chemical processing equipment.
- Custom sizes (e.g., 8 inches): Specialized equipment like tank agitators or heavy-duty rollers.
