PEEK slip ring

PEEK slip ring

Core Features

  • High Dielectric Isolation: PEEK provides exceptional electrical insulation, preventing signal cross-talk and short circuits between rotating conductive paths.
  • Wear-Resistant Matrix: When processed as a “Bearing-Grade” composite, the slip ring maintains low friction and high durability during continuous 360° rotation.
  • Thermal Stability: Retains precise dimensional tolerances and structural integrity in continuous operating temperatures up to 250°C (482°F).
  • Chemical & Corrosion Immunity: Completely immune to aggressive cleaning solvents, saltwater, and organic acids, preventing the ring from seizing or degrading in harsh environments.
  • Low Outgassing & Purity: Manufactured from 100% virgin or reinforced PEEK to ensure zero particulate contamination, essential for ultra-high vacuum (UHV) and clean-room applications.

At Kriloha Ltd., we understand that in rotary power and signal transmission, the stability of the insulating substrate is the primary factor in system longevity. Our PEEK Slip Rings are our engineered answer for “Interruption-Free-Rotation” and “Total-Environmental-Isolation”. As a premier manufacturer of customized polymer solutions, Kriloha has developed a specialized processing protocol to ensure our slip rings deliver the highest levels of dielectric security and mechanical reliability.

The engineering of our slip rings is founded on Geometry-Precision and Surface-Integrity. By utilizing state-of-the-art 5-axis CNC machining, we eliminate the structural weaknesses and parting lines found in molded parts, ensuring perfectly concentric paths for conductive brushes. At Kriloha, we verify the dimensional stability of every ring under thermal load, resulting in “Failure-Resistant” rotary interfaces that maintain their pitch and insulating properties through millions of cycles.

Manufacturing these advanced dynamic components involves strict Dimensional, Thermal, and Insulation Verification. We collaborate directly with your engineering teams to process bespoke configurations—including integrated wiring channels, proprietary mounting tabs, and non-standard diameters—ensuring the slip ring perfectly integrates with your proprietary hardware. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that optimizes your system’s reliability through superior material performance.

Primary Use Cases

  • Medical Diagnostic Equipment: Non-magnetic and radiolucent slip ring assemblies for MRI and CT scanners where signal clarity is paramount.
  • Aerospace & Satellite Systems: Lightweight, high-strength rotary joints for avionic sensors and communication arrays exposed to extreme altitudes.
  • Semiconductor Processing: Precision rotary interfaces used in wafer-handling systems where metallic contamination and static discharge must be avoided.
  • Subsea Robotics (ROVs): Corrosion-resistant electrical interfaces for underwater cameras and propulsion systems exposed to high pressure and saltwater.
  • High-Temperature Industrial Machinery: Rotating electrical connectors for furnaces, glass manufacturing, and chemical mixing vats.

Frequently Asked Questions

Why use PEEK for a slip ring instead of standard Nylon or PTFE?

Nylon and PTFE are prone to “creeping” or deforming under heat and mechanical stress, which can lead to brush misalignment. PEEK provides the structural rigidity of a metal with the electrical insulation of a high-end polymer.

Can Kriloha integrate conductive tracks into the PEEK ring?

As a customization specialist, we machine the precise grooves and cavities required for your conductive inserts. We can also manufacture the primary PEEK housing to accommodate press-fitted metal contacts.

Is PEEK safe for high-vacuum and clean-room rotary applications?

Absolutely. PEEK has exceptionally low outgassing properties and does not shed particulates, making it the industry standard for semiconductor and aerospace vacuum chambers.

How does PEEK handle the friction heat generated by the brushes?

PEEK maintains its mechanical strength up to 250°C, ensuring that the friction heat generated by the conductive brushes does not melt or warp the housing.

Are custom sizes available for proprietary robotic joints?

Yes. We utilize precision CNC machining to achieve sub-millimeter precision for any custom diameter, wall thickness, or internal channel layout required by your CAD designs.
