Excellent Wear Resistance
Polyurethane wheel has excellent wear resistance and can maintain a long service life in various harsh environments. Compared with traditional rubber casters, polyurethane casters have more advantages when it comes to withstanding high-intensity friction and wear, effectively reducing the frequency of replacement and maintenance, and saving costs for enterprises.
Resistant to Chemical Corrosion
The polyurethane material has good chemical corrosion resistance and can resist the erosion of various acid and alkali substances. In chemical, pharmaceutical and other industries, this characteristic makes polyurethane casters an ideal choice, ensuring stable equipment operation.
High Load-bearing Capacity
Polyurethane wheel has a high load-bearing capacity and can withstand the pressure of heavy objects. In logistics and warehousing where heavy objects need to be frequently moved, polyurethane wheel can provide stable support and ensure safe operation.
Flexible Rotation
The polyurethane wheel has excellent rotation performance and can rotate easily even under load, reducing rotation resistance. This not only improves work efficiency but also reduces the risk of equipment damage.
High Degree of Customization
Polyurethane wheel can be customized according to the specific needs of customers to meet the requirements of different sizes and specifications. In addition, by changing the polyurethane formula and process conditions, the hardness, elasticity and other performance parameters of the casters can also be adjusted to meet the needs of specific application scenarios.
Environmentally friendly
Polyurethane material can be recycled and reused, complying with environmental protection requirements. Using polyurethane casters helps reduce carbon emissions and achieve green production.
Easy installation
Polyurethane wheels are compact and easy to install without the need for complicated tools and equipment. This greatly reduces installation costs and time, making it easier for users to put it into use quickly.
Low maintenance cost
Polyurethane wheels are low maintenance in daily use. Due to its excellent wear resistance and resistance to chemical corrosion, users can keep it in good condition with simple cleaning and lubrication. This helps reduce business operating costs.
Crowned Wheels
Crowned poly wheels offer significantly reduced rolling resistance compared to standard flat-treaded wheels. They typically range from 100 to 200 mm in diameter and feature a silent-running urethane tire encasing a lightweight aluminum center.
They are also resistant to solvents and abrasive wear, featuring precision ball bearings for extended bearing life. With a load capacity of up to 600 kg, they are commonly used in conveyor systems.
Desk Wheels
These wheels are commonly found in document processing equipment, where they help orient documents for improved optical reading. Desk wheels are often used in light roller applications and can be designed as soft-touch wheels with varying spring rates, achieved through different urethane harnesses.
Compliant Wheels
Compliant wheels enhance the abrasion resistance of industrial machinery and are used in applications that handle documents or materials of varying thicknesses. Their spring-like motion allows the equipment to process papers of different thicknesses without the need for expensive spring mechanisms.
Drive Wheels
Urethane drive wheels are particularly common due to their adaptability to any required hardness for specific applications. These wheels typically use a key slot or bolt to attach to a hub. They are widely employed in various industries for efficiently moving large items and are especially effective when directional changes are needed.
Engraved Wheels
These wheels feature engraved patterns, such as brand names, identification marks, or serial numbers. They have higher rolling resistance compared to crowned wheels, as they are standard flat-treaded wheels. Available in various sizes, they typically have a lower load capacity.
Application of PU Wheels
PU wheels have proven particularly effective in equipping transport carts, sack trucks, and similar logistical equipment. Thanks to their sturdy construction, PU wheels also offer high operational safety and minimize the risk of failures. Their slip-resistant properties ensure reliable grip on different surfaces, thereby increasing workplace safety.
PU wheels also prove their worth in demanding gardening and landscaping, where they demonstrate their versatility. Specifically designed for uneven and soft terrain, these wheels offer optimal performance for wheelbarrows, sack trucks, and other mobile gardening equipment. Their robust construction ensures stability and longevity, even under challenging conditions. Another advantage of PU wheels is their high resistance to most chemicals, making them particularly suitable for use in environments where they come into contact with fertilizers and other typical gardening substances.
Puncture-resistant PU wheels are also ideal for cleaning equipment and building dryers, as they are resistant to many cleaning agents. Moreover, they are gentle on various types of flooring and have puncture protection.
For mobile soccer goals and marking carts, PU wheels ensure reliable mobility on various surfaces such as grass, artificial turf, or cinder fields. Their robustness and puncture resistance enable easy movement of goals, significantly increasing flexibility during training and matches. For marking carts, the smooth-running and precise PU- wheels also ensure exact line markings. Thanks to their resistance to moisture and many chemical substances, they are suitable for use with various marking paints.
PU wheels are particularly effective in children's play vehicles and transport solutions for toddlers. For handcarts, they provide a stable and safe basis for excursions and outdoor activities. For pedal vehicles, PU wheels offer optimal grip and easy maneuvering, supporting children's motor development. Their use in cribs is particularly noteworthy: Here, the robust PU wheels reliably support the weight of several children while allowing caregivers to easily push and steer. The smoothness of the wheels also ensures a pleasant and safe transport for the little ones.

Manufacturing process of PU wheels
The manufacturing process of polyurethane wheels involves several steps, including the preparation of the metal insert, pouring the Polyurethane, and post-processing. Here is a step-by-step overview of the process:
Preparing the metal insert:
The first step in the manufacturing process is to prepare the metal insert. This is typically done by shot blasting the surface and preheating it before pouring the Polyurethane. This helps to ensure that the Polyurethane adheres properly to the metal insert.
Pouring the Polyurethane:
The next step is to pour the Polyurethane into the mold. This is done using a two-part Polyurethane system that consists of an isocyanate and a polyol. The two components are mixed together to create a reaction that results in the formation of Polyurethane.
Post-processing:
After the Polyurethane has been poured and has cured, the mold is removed and the Polyurethane wheel is ready for post-processing. This may include cutting the Polyurethane to size, trimming any excess material, and adding any necessary components such as bearings.
