What are Polyurethane Casters?
Polyurethane casters are undriven wheels made from polyurethane, designed for attachment to the bottom of large objects to enable movement.
How Polyurethane Casters Are Made
The process of making polyurethane casters involves:
In this technique, the two-part polyurethane is mixed to produce a uniform mixture. The mixture will then be de-gassed and poured into an open mold. The setting of the mixture occurs quickly, so it is important that the process is conducted as quickly as possible and the material is mixed in small batches to avoid wastage.
This process is almost similar to the process of open molding. However, the entire process is conducted in a casting machine. This will save a lot of time and provide a more consistent final product.
Spraying and Coating
This process is a simple one. The polyurethane is sprayed onto a component so that a coating of polyurethane is provided.
This process is generally used for thermoplastic materials. Polyurethane pellets are fed into a reciprocating injection molding machine and melted by the heated reciprocating screw.
At the same time, the liquid material is fed through the machine and injected into a mold. The material is allowed to cool down and then removed from the mold.
The machining of most grades of polyurethane can be done using conventional methods like turning, grinding, milling and drilling. However, for softer materials, special techniques are required. One technique that can be used for softer materials is freezing the material before machining so its hardness can be increased.
Machining to relatively high tolerances is possible when using hard polyurethane. The material can be improved further by using the grinding process.
Types of Polyurethane Casters
The different types of polyurethane casters include:
Medium Duty Polyurethane Caster
These types of casters cost less. They consist of a highly resistant steel bracket that is pressed. They are non-marking, and they exhibit good abrasion resistance. In addition, they have good dampening with a low resistance to rolling.
They are capable of carrying high loads, especially at low speeds. They are resistant to multiple diluted acids, oils, greases, and alkalis.
Medium Duty Polyurethane on Polypropylene Caster
These consist of a double ball bearing. They offer non-marking tread and excellent resistance to abrasion. They also offer excellent resistance to impact and exhibit high resistance to greases and oils.
Medium Duty Polyurethane on Aluminum Caster
These have a robust center of aluminum bonded with a tread of cast polyurethane. They are non-marking, and they exhibit properties of abrasion and impact resistance.
Heavy Duty Polyurethane Caster with Cast Iron Center
These have a strong center made from cast iron and are bonded with a high-grade polyurethane tread; they also consist of strong pressed steel brackets with a chromate and zinc finish. They offer a non-marking tread and excellent abrasion and impact resistance. They are also resistant to greases and oils.
Applications and Benefits of Polyurethane Casters
The applications and benefits of polyurethane casters include:
Applications of Polyurethane Casters
- Overhead Conveyor Systems
- Industrial Carts
- Industrial Washer Systems
- Roll forming Machinery
Benefits of Polyurethane Casters
The benefits of polyurethane casters include:
Polyurethane casters are used in a variety of industries to reduce noise levels. Polyurethane casters are considerably quieter compared to cast iron or steel. The polyurethane acts like a shock absorber on a terrain that is uneven.
Dynamic Load Bearing Capability
Compared to rubber casters, polyurethane casters offer a higher load-bearing capacity. They also offer good compressive deformation behavior.
Polyurethane casters function efficiently and are generally non-marking. They function well on hard surfaces such as concrete, even hardwood, and ceramic tiles. They reduce direct stress on a floor because of their large surface area and shock absorption.
High Grip and Traction
Polyurethane casters provide less resistance than others, making them some of the most ergonomic on the market. In addition, polyurethane casters have properties that allow for improved grip and traction compared to other hard wheels. They also reduce the quantity of load on the wheel for the achievement of the desired driving force.
Resistance to Corrosion
Polyurethane wheels are resistant to corrosion and a multitude of chemicals like greases, oils, and cleaning agents found in industrial and commercial environments.
Choosing the Right Polyurethane Caster Manufacturer
To make sure you have the most productive outcome when purchasing polyurethane casters from a polyurethane caster manufacturer, it is important to compare at least 4 to 5 companies using our list of polyurethane caster companies. Each polyurethane caster manufacturer has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each polyurethane caster company website using our patented website previewer to get an idea of what each business specializes in, and then use our simple RFQ form to contact multiple polyurethane caster companies with the same quote.
