Customization of PEEK products

At Kriloha Ltd., we understand that industrial mobility in extreme environments demands more than standard off-the-shelf solutions. When polyurethane melts and steel wheels destroy your expensive tracks, our PEEK Wheel Customization service is our engineered answer for “Zero-Contamination-Mobility” and “Dynamic-Load-Optimization.” As a premier provider of advanced polymer components, Kriloha has developed a dedicated custom-fabrication division that translates your unique kinematic requirements into physical, high-performance reality.

The engineering of our custom PEEK wheels is based on Rotational-Concentricity and Load-Distribution. A wheel that wobbles or deforms under pressure causes catastrophic system failure. By utilizing advanced 5-axis CNC machining, we ensure sub-millimeter tolerances for concentricity (runout) and perfectly dimensioned bearing housings. At Kriloha, we verify the structural integrity of every custom tread profile—whether it is a complex V-groove for a wire-guide or a heavy-duty flat roller. This creates a “Failure-Resistant” dynamic component that glides seamlessly without shedding particulates or corroding.

Manufacturing these advanced polymer components involves strict Dimensional, Thermal, and Material Verification. We collaborate directly with your engineering teams to determine whether virgin PEEK or specialized formulations—like Bearing-Grade PEEK (blended with PTFE and graphite for extreme low-friction)—are required to meet your specific load and speed requirements. Whether you are prototyping a single bespoke wheel for an experimental medical device or scaling up production for a clean-room conveyor line, Kriloha provides the exact kinematic durability your facility demands. By choosing Kriloha Ltd., you are investing in a “Future-Proof” manufacturing partnership that keeps your most critical innovations moving.

Primary Use Cases

Semiconductor Wafer Handling: Clean-room robotics and track systems where wheels must generate zero particulates (dust), exhibit extremely low outgassing, and resist harsh chemical washes.
Medical & Diagnostic Equipment: Non-magnetic, radiolucent guide wheels and casters for MRI machine patient beds, surgical robotics, and high-temperature sterilization autoclaves.
High-Temperature Ovens & Conveyors: Roller wheels and guide tracks operating continuously in extreme heat environments where standard urethane, nylon, or rubber wheels would rapidly melt or degrade.
Food & Beverage Processing: Sanitary conveyor systems requiring frequent high-pressure steam cleaning (hydrolysis resistance) and absolute immunity to acidic food compounds and caustic washdowns.
Aerospace & Avionic Tracks: Lightweight, high-strength guide wheels for sliding mechanisms, payload tracks, and doors where weight shedding and zero-corrosion are critical parameters.

Frequently Asked Questions

Why use a custom PEEK wheel instead of a standard polyurethane or steel wheel?

Standard polyurethane or rubber wheels will flatten, melt, or degrade at high temperatures or in harsh chemical environments. Steel wheels can survive the heat but will often gouge, scratch, and eventually destroy softer metal tracks, while also generating metal dust. PEEK bridges the gap: it survives extreme heat and chemicals like metal, but protects tracks and runs silently like plastic.

How do you ensure the wheel won’t wobble at high rotational speeds?

Wobble (or runout) is caused by poor machining tolerances. At Kriloha, we utilize high-precision CNC lathes to turn the wheels from solid, stress-relieved rods of PEEK. This ensures the outer diameter and the inner bearing bore are perfectly concentric, providing smooth, vibration-free rotation even at high RPMs.

Can you manufacture PEEK wheels with integrated bearings?

Yes. The most common customization request is designing the wheel hub to perfectly house a specific bearing. We machine the bore to exact press-fit tolerances. For completely non-magnetic or ultra-corrosive environments, we can even integrate full-ceramic or PEEK ball bearings into the wheel assembly.

What is “Bearing-Grade” PEEK, and should I use it for my wheels?

Bearing-Grade PEEK (often black in color) is a specialized formulation blended with carbon fiber, graphite, and PTFE to drastically lower the coefficient of friction and improve wear resistance. It is excellent for sliding components or wheels that might experience lateral scraping. However, for pure heavy-duty rolling, virgin PEEK often provides superior impact strength. Our engineers will help you choose the correct matrix.

Can you make specific V-groove or U-groove track profiles?

Absolutely. Because these are custom-machined to your CAD models, we can cut any complex geometry into the outer diameter of the wheel to ensure it mates perfectly with your proprietary wire, rail, or pipe systems.
