PEEK (Polyether Ether Ketone) balls are utilised in various industrial and technical applications across the United Kingdom and around the world due to their exceptional material properties.
Available in sizes (In) - 3/32", 1/8", 5/32", 3/16", 7/32", 1/4", 9/32", 5/16", 3/8", 7/16", 1/2", 9/16", 5/8", 3/4", 1"
Here's an overview of what PEEK balls are used for and why PEEK is selected for these applications:
1. Bearings and Bushings: PEEK balls are employed in the manufacturing of bearings and bushings. PEEK's properties, including high mechanical strength, low friction coefficient, and resistance to wear and corrosion, make it an excellent choice for applications where smooth, reliable rotation or movement is crucial. PEEK's dimensional stability also ensures that bearings maintain their integrity over time.
2. Check Valves: Check valves, used to control the flow of fluids in pipelines, often benefit from the use of PEEK balls. PEEK's chemical resistance, high-temperature stability, and durability make it suitable for critical applications, particularly in industries such as chemical processing and petrochemicals. Its resistance to aggressive chemicals helps ensure the long-term reliability of check valves.
3. Medical Devices: PEEK balls are integral components in a range of medical devices and equipment. PEEK is chosen for these applications because of its biocompatibility and resistance to sterilisation methods, such as autoclaving. These properties make PEEK balls suitable for use in check valves, pumps, and flow control systems in medical devices, ensuring they meet stringent quality and safety standards.
4. Aerospace: In the aerospace industry, PEEK balls are utilised where lightweight, high-strength materials are crucial. They can be found in aerospace bearings, actuator components, and control systems. PEEK's resistance to aviation fluids and its ability to maintain mechanical integrity in extreme temperature conditions make it a preferred material in aerospace applications.
5. Electronics: PEEK balls are used in precision electronic components such as ball bearings, electrical connectors, and switches. Their electrical insulating properties, coupled with their mechanical strength, make them valuable in the electronics industry. PEEK's dimensional stability and resistance to thermal cycling are particularly advantageous in electronic applications.
6. Oil and Gas: In the oil and gas sector, PEEK balls are used in downhole tools, well completion equipment, and control systems. PEEK's resistance to aggressive chemicals, including oilfield fluids, and its ability to withstand high-pressure conditions make it a reliable choice in these demanding applications.
7. Automotive: PEEK balls can be found in various automotive components like ball joints, fuel system parts, and air conditioning systems. Their ability to withstand automotive fluids, resist wear, and provide mechanical stability in the often harsh conditions of automotive systems is a key advantage.
8. General Engineering: PEEK balls are utilised in a wide range of general engineering applications, including flow control devices, pumps, and machinery components. Their versatility, high-temperature resistance, chemical compatibility, and exceptional mechanical properties make them valuable in diverse engineering settings.
