PEEK bushing

At Kriloha Ltd., we understand that a bushing is the silent guardian of mechanical longevity. Our PEEK Bushings represent our engineered answer for “Friction-Reduction-Security” and “Maintenance-Free-Integrity.” As a premier manufacturer of customized polymer solutions, Kriloha has established a high-precision fabrication protocol to ensure that every bushing provides a superior interface between moving components.

The engineering of our bushing program is founded on Concentricity-Precision and Material-Optimization. By utilizing state-of-the-art 5-axis CNC machining, we eliminate the internal stresses and dimensional “drift” often found in molded bushings. At Kriloha, we verify the internal and external tolerances ($I.D./O.D.$) of every bespoke bushing, resulting in “Failure-Resistant” components that replace heavy bronze or steel bushings and eliminate the need for external grease or oil.

Manufacturing these advanced polymer components involves strict Dimensional Verification, Hardness Testing, and Surface-Roughness ($R_a$) Calibration. We collaborate directly with your engineering teams to process bespoke configurations—including integrated flange designs, internal lubrication grooves, and reinforced PEEK grades (such as Carbon-Filled or PTFE-Lubricated). By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that prioritizes your system’s uptime through superior material science.

Primary Use Cases

Analytical Instruments: Precision bushings for moving parts in HPLC and laboratory equipment where high purity and chemical inertness are mandatory.
Food & Beverage Machinery: FDA-compliant, grease-free bushings for conveyors and filling lines to prevent food contamination.
Aerospace Actuators: Lightweight, thermally stable bushings for flight control surfaces and landing gear components.
Subsea Equipment: Corrosion-proof bushings for underwater valves and ROV (Remotely Operated Vehicle) joints exposed to high hydrostatic pressure.
Medical Diagnostic Devices: Non-magnetic and autoclave-safe bushings for MRI-compatible hardware and surgical robotics.

Frequently Asked Questions

Why use a PEEK bushing instead of a Bronze or Brass bushing?

Metal bushings require constant lubrication to prevent seizing and are prone to corrosion. PEEK bushings are self-lubricating, 70% lighter, and chemically inert, making them ideal for “set-and-forget” applications in harsh or sterile environments.

Can Kriloha manufacture “Flanged” PEEK bushings?

Absolutely. We specialize in precision CNC machining and can produce flanged bushings that provide both radial support and axial thrust bearing in a single, integrated component.

Is PEEK safe for bushings that undergo repeated steam sterilization?

Yes. PEEK features phenomenal resistance to hydrolysis. Our bushings maintain their dimensional accuracy and low-friction properties through thousands of high-pressure steam autoclaving cycles.

How does PEEK handle “Dry-Running” without lubrication?

PEEK is a tribologically superior material. For extreme dry-running or high-speed applications, we can provide PTFE-filled or Graphite-filled PEEK grades that further reduce friction and heat buildup at the interface.

Are custom sizes available for non-standard shaft diameters?

Yes. We utilize precision CNC technology to achieve sub-millimeter accuracy for any custom internal diameter, wall thickness, or specialized geometry required by your proprietary CAD designs.
