It is important to find the right material for casting because only the material that suits your needs will help you to be efficient and safe at the same time. Casters have definitely made our lives easier. Let us take a look at some of the typical caster wheel materials that are out there and where they are most effective.

1. Swivel casters made of polypropylene

A thermoplastic material such as polypropylene has many properties, including shock resistance, corrosion resistance, friction resistance, non marking, non staining, and nontoxic properties, as well as being odorless and not absorbing moisture. With the exception of strong oxidizers and halogen hydrogen compounds, polypropylene is resistant to many corrosive substances. A temperature range of -20°C to +60°C is applicable, though a temperature exceeding +30°C decreases bearing capacity

2. Swivel casters with nylon wheels

Known for its corrosion and friction resistance, odorless and non-toxic structure, and non-marking and non-staining properties, nylon is a thermoplastic. Despite its ability to resist corrosive substances, nylon will not be able to withstand chlorine hydrogen compounds or heavy metal salt solutions. Due to its temperature range from -45°C to +130°C, it can be used in high temperature environments for short periods of time. Although the bearing capacity decreases at ambient temperatures above +35, it should be noted. Get more info about footmaster leveling casters.

3. Swivel caster with polyurethane wheels

Among the thermoplastic polyurethane family, polyurethane (TPU) protects the ground and absorbs vibrations with its non-marking, non-staining properties. It has outstanding friction and corrosion resistance, as well as excellent elasticity, making it ideal for a wide range of environments. Customers can choose the colors of the polyurethane to match required uses, with an applicable temperature range between -45℃ and +90℃, though it should be noted that the bearing capacity decreases at ambient temperatures higher than +35℃. The hardness is generally 92°±3°, 94°±3° or 98°±2° Shore A.

4. Cast Polyurethane (CPU) Elastomer Wheels for Swivel Casters

The cast polyurethane elastomer is a thermosetting polyurethane elastomer that is formed by chemical reaction. In addition to protecting the ground, this material offers excellent abrasion, corrosion, and UC radiation resistance, as well as excellent elasticity. However, it is important to note that this material is not resistant to hot water, steam, humid air, or aromatic solvents. Casting polyurethane elastomers perform best at ambient temperatures below -10°C, and their hardness is 75°+5° Shore A at temperatures between -30°C and +70°C.

5. Casting Polyurethane (CPU) Wheel Swivel Caster

With a chemical reaction, casting polyurethane is formed, a thermosetting polyurethane elastomer. Customers can choose colors based on their requirements, and it is particularly suitable for applications with a maximum speed of 16km/h. During short-term use, the temperature can reach as high as 90°C, but the application temperature ranges between -45°C and +90°C.

6. Swivel caster made of nylon (MC)

A thermosetting plastic, casting nylon (MC) is formed through a chemical reaction, and has a natural color. It has a very low rolling resistance and a natural color. The temperature range for casting nylon is between -45°C and +130°C. However, at temperatures above +35°C, bearing capacity will decrease.

7. Wheel casters made from foam polyurethane (PUE)

When it is used in high strength and pressure applications, foam polyurethane (PUE), also called microcellular polyurethane, provides a great level of buffering, a property that is not available in plastics or rubber.

8. Tires are made of solid rubber

By wrapping high quality rubber around the outer rim of the wheel core, solid rubber tires are formed by vulcanizing them at high temperatures. As well as offering excellent shock absorption and impact resistance, solid rubber tires also have excellent ground protection and erosion resistance. Among our solid rubber tire colors are black, gray, and dark grey, which are applicable from -45°C to +90°C and have a Shore A hardness of 80°+5°/-10°.

9. Casters with pneumatic wheels

A pneumatic wheel caster includes pneumatic tires and rubber tires, both made from rubber. They protect the ground and are especially useful in poor ground conditions. The temperature range is between -30°C and +50°C.

10. Rubber Wheel Casters

These soft rubber wheel casters protect the ground, especially in poor conditions. The temperature range is -30°C to +80°C, and the hardness is 50°+5° Shore A.

11. Rubber wheel casters

In order to protect equipment, goods, and the floor, synthetic rubber wheel casters are made of thermoplastic rubber elastomers (TPR), which offer excellent cushioning and shock absorption. With superior performance to cast iron core rubber wheels, it can be used in ground environments with gravel or metal filings. It is suitable for temperatures ranging from -45°C to +60°C. It has a hardness of 70°±3° Shore A.

12. Synthetic rubber antistatic wheel casters

This antistatic synthetic rubber wheel caster is constructed of thermoplastic rubber elastomer (TPE), and features a static resistant performance. The applicable temperature range is between -45°C and +60°C, and the hardness is 70°±3° Shore A. For more info about heavy duty self leveling casters, Visit our website.

13. Cast Iron Wheel Caster

Wheel casters made of cast iron have a high bearing capacity and can withstand a temperature range of -45°C to +500°C, with a hardness of 190-230HB.

Each material has its own characteristics, so it is crucial to choose the most suitable wheel material for your business. If you take the time to choose the right material, you will get the best results and experience possible. We recommend that you also consider the wheel bearing after choosing the right material, since it is an important factor to consider.
