Our premium Polyurethane (PU) Stacker Crane Wheels are precision-engineered to meet the rigorous demands of heavy-duty, high-frequency logistics environments, effectively solving common issues such as premature tread wear, vibration, and excessive noise.
Core Technical Advantages
Our wheels are crafted using advanced MDI-based polyurethane elastomers. Through precision centrifugal casting and meticulous post-curing processes, we achieve the ultimate balance between durability and mechanical performance.
Exceptional Wear Resistance: Our specialized PU formula offers over 40% higher abrasion resistance compared to standard rubber or low-grade PU, significantly extending replacement intervals and reducing operational downtime.
Superior Bonding Strength: Utilizing a proprietary chemical bonding process, we ensure an unbreakable link between the polyurethane tread and the metal core, preventing delamination even under intense acceleration and braking cycles.
Low Rolling Resistance & Heat Generation: Optimized for energy efficiency, our wheels minimize internal heat build-up during high-speed, continuous operation, protecting the material from thermal softening.
Noise & Vibration Damping: The high-elasticity material naturally absorbs shocks and vibrations, ensuring whisper-quiet operation and protecting sensitive electronic components on your crane.
Optimal Load-Bearing & Traction: With an engineered Shore A 95-98 hardness range, our wheels provide the perfect balance between high load-carrying capacity and essential grip for precise positioning.

Applications
Our PU wheels are the trusted choice for critical industrial logistics infrastructure:
AS/RS Systems: Driving and support wheels for stacker crane carriages and lifting masts.
AGV / AMR Systems: Heavy-duty transport platforms requiring long-lasting reliability.
Industrial Conveyors: High-load, high-speed roller systems.
Precision Machinery: Heavy equipment requiring smooth, vibration-free movement.
Customization & Quality Commitment
We understand that every warehouse project is unique. We offer comprehensive, tailored solutions:
Full-Range Customization: We offer diameters from 80mm to 800mm and support bespoke hub designs based on your technical drawings.
Environmental Optimization: Need specific performance for cold storage (freezers), high-humidity, or dusty environments? We can adjust our chemical formulas to enhance hydrolysis or low-temperature resistance.
Stringent Quality Control: Every wheel undergoes rigorous compression, dynamic fatigue, and dimensional tolerance testing before shipment.
Expert Tip: When selecting stacker crane wheels, do not base your choice on static load alone; consider the cycle frequency and ambient temperature. Regular inspection of your track surface is also highly recommended to maximize the lifespan of your PU wheels
Your Partner in Industrial Wheel Solutions
In-House Material Formulation: We develop our own polyurethane compounds, allowing us to balance load capacity, wear resistance, and noise reduction based on specific application requirements. Our laboratory testing ensures that the material properties remain stable under real-world conditions.
Precision Processing: Our manufacturing facility utilizes high-precision CNC equipment to ensure that every wheel meets the exact dimensional tolerances required by your system. This minimizes vibration and prevents unnecessary stress on the track infrastructure.
Quality Management: We maintain a quality management system. Each production batch undergoes standardized testing—including hardness verification, load-bearing assessment, and bond strength analysis—to ensure the consistency our clients expect.
Collaborative Approach: We focus on providing technical support that helps your maintenance team optimize performance. Whether it is analyzing wear patterns or adjusting wheel geometry for a specific conveyor section, our engineering team is available to work through your operational challenges.
Reliable Supply: We understand that equipment uptime is critical. By maintaining streamlined production and a steady supply of raw materials, we provide consistent lead times and dependable fulfillment for facility upgrades and routine maintenance cycles.
