Heavy Duty Polyurethane-Driven Wheel
The polyurethane-driven wheel itself does not provide power, but is driven by the driving wheel, and has the functions of transmitting motion, supporting and guiding, and sharing loads.

Technical Information
Polyurethane-driven wheel refers to the wheel that plays the following role and transmits power or motion in the mechanical transmission system: Unlike the driving wheel, the driven wheel does not provide power directly but realizes its own movement by contacting it and rotating it. In many mechanical equipment, the driven wheel is often used to carry and guide the task of transporting or conveying materials and loads, playing a key role in deceleration, load balancing, and adjusting the trajectory of movement.
Benefits of polyurethane as a driven wheel
• Strong wear resistance
Idler wheels with bearings can maintain good shape and performance in long-term high-intensity friction and rolling. In logistics warehousing forklift applications, the wear of polyurethane-driven wheels under frequent starting, stopping, and turning is much lower than that of traditional rubber wheels, reducing the need for frequent replacement and maintenance, reducing maintenance costs, shortening downtime, and thus improving production efficiency.
• High load-bearing capacity
Polyurethane-driven wheels are important to load sharers of equipment, and together with the driving wheel, they support the weight of equipment and goods, reducing the pressure on the driving wheel. In heavy-duty logistics transportation, the driven wheel bears part of the weight, helping the driving wheel to easily provide power, reducing wear and fatigue, and improving the stability and durability of the transmission system.
• Shock absorption and noise reduction
The elastic properties of polyurethane enable the driven wheel to effectively absorb vibration and impact, reduce noise, and provide smooth operation. This is particularly important in industries such as medicine and electronics, which not only creates a comfortable environment for patients and staff but also avoids noise interference with precision equipment.
• Corrosion resistance and chemical resistance
Polyurethane has excellent corrosion resistance and chemical resistance and can resist erosion by chemicals such as oils, acids, alkalis, greases, and solvents, and adapt to harsh working environments. In chemical production, polyurethane-driven wheels can work stably in chemical environments, ensuring the normal operation of equipment, and broadening its application range in complex industrial environments.
• Low friction coefficient
The low friction characteristics of polyurethane make the driven wheel require less power during movement, which can improve the efficiency of equipment and reduce energy consumption.
• Strong adaptability
Polyurethane can adjust its hardness according to different needs to adapt to the requirements of different working environments. For example, polyurethane with higher hardness is suitable for heavy-duty environments, while softer polyurethane is suitable for precision equipment that requires lower friction.
