WHEELS
Polyurethane wheels have all the advantages of rubber, plastic and metal. They have excellent mechanical and chemical properties compared to other materials making it a very popular choice in the selection process.
PROPERTIES
Additional properties of polyurethane wheels include resistance to impact, abrasion and tear, shock absorption qualities, ease of customization, minimal heat build-up, hydrolysis resistance, and low-temperature performance, reduction in noise pollution, resistant to ultraviolet radiation, they are flexible and non-corrosive. They come in a wide range of hardness – from 20 Shore A to 80 Shore D.
A wide selection in soft, hard, rigid and integral skin options gives polyurethane an absolute advantage over all other options in both rubber and plastics.
Polyurethane wheels are manufactured using the casting, hydraulic press molding or injection molding process. The wheels come in complete solid polyurethanes and for more heavy duty applications comes with an inner core consisting of either cast iron, aluminum or steel structure.
The outer tread consists of polyurethane material, this helps the polyurethane wheels to function as a good shock absorber and cushioning agent helping it work efficiently on bumpy and uneven terrains while keeping the noise level dramatically low.
Polyurethane wheels have a higher load bearing capability, higher tensile strength and wear resistance compared to rubber or plastic wheels. The load capacity of urethane wheels is up to 5 X that of rubber caster wheels with the same dimensions. Polyurethane wheels have higher elastic memory and flexibility compared to plastic wheels. They provide better grip and traction reducing the load on the wheel to provide the required driving force. Each wheel can be customized by hardness, flexibility, tear strength, color and other parameters based on the application demand, this gives polyurethane wheels an unmatched advantage over rubber, plastic and metal wheels.

3. Elevators And Escalators
Elevators and escalators are part of our day to day life. They are a popular mode of transporting people in all public and private arenas. Maintenance and up-keepment of these utilities is paramount to make sure that they work seamlessly. Polyurethane guide wheels and rollers perform a critical role in the smooth flow. Our wheels keep the elevators in place and help them stabilize against the steel guides ensuring that the elevator stays in place to ensure a smooth ride. These wheels also act as an Anti-lock system in case the cable malfunctions. Hence the polyurethane wheels are an integral part in the working of elevators and escalators.
Safety, performance and reliability of the polyurethane wheels under varied working environments is paramount as most escalators and elevators work in high traffic area’s transporting people, any disruption in the service causes logistical problems. Our rollers are manufactured from high quality polyurethanes, capable of handling high load and speed, they have excellent resistance against wear and tear even under extreme weather conditions ensuring long working life. This ensures low maintenance costs on the system which has huge cost savings in the long run.
Our wheels are used in both passenger and service lifts and all types of escalators which are widely used in Shopping Centers, Airports, Hotels, Stadiums, Department Stores, Office Buildings, Arenas, Convention Centers, Train Stations, and Underground Stations.
Having an in-house design and development team helps us to develop custom made products based on individual requirements of each customer. This gives the customer flexibility to change the design or the material based on their specific application requirements.
4. Industrial Wheels

All industrial wheels are machined to the size requirements of each customer, providing keyways and bearings making it ready to use for the customer.
We also offer industrial wheels with softer compounds which are non-marking, good for wet area usage providing good surface grip, are hydrolysis resistant.
Types of Polyurethane Wheels
1. DRIVE WheeL
We manufacture medium to heavy duty drive wheels in high grade Polyurethanes, giving good electrical conductive properties, better wet grip for wet and slippery floors, manufactured in soft and hard compounds based on working conditions of the fork lifts. Our drive wheels come with a keyway or in a stud hole configuration. The inner metal core come in pressed steel or cast iron options. They are extensively used in material handling industries in fork lifts and cargo carts. All wheel tread are non-marking offering good dynamic load capacity, mechanical wear resistance and a good compression set. All polyurethane wheels are resistant to many chemicals and oils having low water absorption which make these wheels ideal for most material handling applications. Our polyurethane drive wheels can handle medium to high load capacities ranging from 1000 Kgs up to 10,000 Kgs. There are different ways to manufacture the wheels – either bonding them directly on the metal core of the fork lift wheel or with an option of press on tire, which can be directly pressed on the metal core for easy replacements.
