INDUSTRIES SERVED: Material Handling , Warehousing & Logistics, Mining Machinary, Construction Machinary, Automotive Assembly Line
We provide NDI-based polyurethane wheels for various applications, such as forklifts, mining machines, driverless transport systems, conveyor systems, harbor/port machinery, construction equipment, automated systems, and other heavy-duty or high speed scenarios.
Our NDI-based polyurethane drive wheels, load wheels, and press-on tyres are supplied to an extremely outstanding standard. They provide best abrasion resistance, excellent dynamic properties, low-noise, and ensure smooth, reliable operation in tough conditions, outperforming other standard polyurethane or rubber options.

De-bonding usually occurs due to poor chemical preparation of the metal core (cast iron or steel). We utilize cleaning process and high-performance bonding agents to ensure a peel strength exceeding 70 N/mm. This ensures the tread remains intact even under high torque, frequent start-stops, and heavy lateral loads.
Polyether: Highly resistant to hydrolysis (moisture), making it ideal for humid environments, cold storage, or outdoor use. It also offers lower heat build-up. Polyester: Provides superior oil and solvent resistance and higher tear strength, best suited for chemical plants or indoor industrial floors. If you are unsure, provide us with your floor conditions, and we will match the chemistry to your environment.
No. Our high-grade non-marking polyurethane formulas are designed to protect expensive industrial flooring. Unlike nylon wheels, PU provides a degree of
Our dynamic ratings are calculated based on a speed of 4 km/h. For instance, a wheel rated for $1,000 kg is tested for continuous movement at that weight, not just its static
This is caused by Hysteresis (Internal Heat Build-up). In high-duty cycle applications, standard PU dissipates energy as heat, leading to material failure. We recommend our High-Resilience (NDI/Vulkollan equivalent) formulas, which feature ultra-low rolling resistance and minimal heat accumulation to prevent thermal breakdown.
Yes. We manufacture wheels using FDA-compliant polyurethane (CFR 21) for food processing. For pharmaceutical cleanrooms, we combine these treads with 304 Grade Stainless Steel cores and precision sealed bearings to withstand rigorous chemical washdowns and prevent corrosion.
While sealed precision ball bearings are standard for low rolling resistance, we recommend Tapered Roller Bearings for applications involving heavy side-loading or high-speed towing. These bearings are designed to absorb axial thrust, ensuring the wheel rotates smoothly during sharp turns under load.
We use automated metering and mixing systems rather than manual pouring. This ensures the prepolymer-to-curative ratio is accurate to within 0.1%. Every batch undergoes random Shore A/D hardness testing, and we provide a Material Test Report (MTR) with every shipment.
While the initial cost may be 20%-30% higher than
