Polyurethane Wheels

Polyurethane wheels have been a staple of the caster industry for years and are one of the most popular wheels. Polyurethane wheels are designed to handle heavy duty weights while providing floor protection, non-marking treads, quieter rolling, and smoother rides. We offer heavy duty polyurethane wheels as well as low profile light duty poly wheels.

Product Introduction

Introduction

Polyurethane is superior to rubber in resistance to grease, oil, cutting, chunking, and abrasive wear. These caster wheels can be used on almost any factory floor. As with moldon rubber, the bonding agent which holds the polyurethane tire ( tread ) to its iron center can be affected by exposure to some chemicals, impact, overloading, and the buildup of heat. Given a manual operation under ideal conditions, polyurethane caster wheels have a safe operating capacity of up to three times the capacity of the same size rubber wheel. Capacity ratings are offered as an idea of what the wheel will carry without failure. They are not absolute, but rather depend on the usage and service.

Applications

Logistics handling equipment

In factories, warehouses and other places, polyurethane wheels are widely used in various logistics handling equipment, such as trolleys, forklifts, stackers, etc. Polyurethane wheels can bear heavy cargo weights and maintain stable operation under different ground conditions, reducing the vibration and noise of equipment and improving work efficiency.

Automated production lines

On automated production lines, polyurethane wheels can be used as the wheels of conveying equipment, such as conveyor belts, rollers, etc. The high precision and low friction coefficient of polyurethane wheels can ensure the smoothness and accuracy of products during the conveying process, reducing product damage and waste.

Machining equipment

Some machining equipment, such as machine tools, milling machines, etc., also use polyurethane wheels as the wheels of moving parts. The wear resistance and impact resistance of polyurethane wheels can ensure the stable performance of equipment during long-term use and reduce the maintenance and replacement costs of equipment.

FAQ

Q: How wear-resistant are polyurethane wheels?

A: Polyurethane wheels have excellent wear resistance. Compared with traditional rubber wheels, polyurethane wheels can be used for a long time under various complex ground conditions without being easily worn, greatly prolonging the service life of the wheels.

Q: What is the load-bearing capacity of polyurethane wheels?

A: Polyurethane wheels usually have a relatively high load-bearing capacity. Different specifications of polyurethane wheels can be selected according to different needs to meet various load requirements. Generally speaking, industrial-grade polyurethane wheels can bear heavier goods and equipment.

Q: Is the noise reduction effect of polyurethane wheels good?

A: Polyurethane wheels generate relatively low noise during operation. Its special material and structural design make the wheels run more smoothly and quietly. They are especially suitable for places with strict requirements for noise, such as hospitals, libraries, shopping malls, etc.

Q: What kinds of ground are polyurethane wheels suitable for?

A: Polyurethane wheels can be used on various grounds, including cement ground, ceramic tile ground, wooden floor, carpet, etc. It has good grip and stability and can adapt to the friction coefficient and hardness of different grounds.

Q: Can polyurethane wheels be used outdoors?

A: Polyurethane wheels can be used outdoors, but the impact of environmental factors on the wheels needs to be considered. For example, in harsh environments such as high temperature, low temperature, and humidity, the performance of polyurethane wheels may change. At the same time, when used outdoors, attention should be paid to avoiding scratches and damage to the wheels by sharp objects.

Q: How tolerant are polyurethane wheels to chemicals?

A: Polyurethane wheels have a certain tolerance to general chemicals, but for strong corrosive chemicals such as strong acids and alkalis, the wheels may be damaged. During use, if it is necessary to contact chemicals, it is recommended to understand the tolerance of polyurethane wheels to the chemical first.

Q: Is the installation of polyurethane wheels complicated?

A: The installation of polyurethane wheels is relatively simple. Generally, wheels can be installed on equipment through connectors such as bolts and nuts. During the installation process, it is necessary to ensure that the wheels are firmly installed to ensure the safe operation of the equipment.

Q: How to maintain polyurethane wheels?

A: In order to prolong the service life of polyurethane wheels, proper maintenance is required. Clean the wheels regularly to avoid dust and debris from accumulating on the surface and inside of the wheels. Check the wear condition of the wheels and replace severely worn wheels in time. During use, avoid overloading and high-speed driving to reduce the wear and damage of the wheels.
