PEEK bearings

At Kriloha Ltd., we recognize that in specialized environments, traditional metal bearings are often the weakest link. Our PEEK Bearings represent our engineered answer for “Contamination-Zero-Security” and “Extreme-Environment-Integrity.” As a premier manufacturer of high-performance polymer solutions, Kriloha has developed a specialized assembly protocol that combines precision-machined PEEK races with high-performance ball materials to suit your specific load requirements.

The engineering of our bearing program is founded on Tribological-Optimization and Material-Purity. By utilizing state-of-the-art CNC machining for the races, we achieve sub-millimeter tolerances that ensure smooth rotation and reduced vibration. At Kriloha, we typically configure these bearings with Ceramic (Zirconia or Silicon Nitride) balls or Glass balls, creating a completely non-metallic assembly that is “Failure-Resistant” in environments that would destroy standard steel components in days.

Manufacturing these advanced polymer bearings involves strict Radial-Play Calibration, Thermal-Testing, and Surface-Finish Verification. We collaborate directly with your engineering teams to process bespoke configurations—including deep-groove ball bearings, thrust bearings, and custom-dimensioned housings. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that optimizes your system’s reliability through superior material science.

Primary Use Cases

Medical & Diagnostic Imaging: Non-magnetic bearings for MRI scanners and surgical robotics where metallic interference must be zero.
Semiconductor Processing: High-purity bearings used in wafer handling and chemical bath tools where outgassing and metallic ions must be avoided.
Chemical Processing & Pumps: Corrosion-proof bearings for submerged pumps and flow meters handling aggressive reagents.
Food & Beverage Production: FDA-compliant bearings for bottling and packaging lines where regular wash-downs with harsh chemicals are required.
Marine & Subsea Sensors: Long-life bearings for underwater equipment exposed to high hydrostatic pressure and permanent saltwater immersion.

Frequently Asked Questions

What are the balls made of in a PEEK bearing?

Since PEEK bearings are usually chosen for their chemical or non-magnetic properties, we typically use Ceramic balls (ZrO2 or Si3N4), Glass balls, or even PEEK balls for low-load applications. This ensures the entire assembly remains corrosion-proof.

Can PEEK bearings handle the same loads as steel bearings?

No. While PEEK is incredibly strong for a polymer, it has lower load-carrying capacity than hardened steel. They are designed for applications where corrosion resistance, low weight, or non-magnetic properties are more important than heavy structural loading.

Is PEEK safe for high-speed rotations?

Yes, but heat dissipation must be considered. Because PEEK is a thermal insulator, we often recommend carbon-filled grades or ceramic balls to help manage frictional heat in high-RPM “dry-running” scenarios.

Are these bearings suitable for “Wash-down” environments?

Absolutely. PEEK is highly resistant to the aggressive detergents and high-pressure steam used in food and pharmaceutical facility cleaning cycles (CIP/SIP).

Can Kriloha manufacture custom-sized bearings for non-standard housings?

Yes. Unlike standard off-the-shelf bearings, we specialize in precision CNC machining, allowing us to produce bearings with custom inner/outer diameters and widths to fit your proprietary equipment perfectly.
