Casters have made our lives significantly easier. Choosing the right material is crucial for efficiency and safety, as each material has its own pros and cons. Here are some common caster wheel materials and their best applications:
1. Polypropylene Wheel (PP Wheel)
Properties: Shock, corrosion, and friction resistant; non-marking, non-toxic, odorless.
Temperature Range: -20℃ to +60℃ (bearing capacity decreases above +30℃).
2. Nylon Wheel
Properties: Corrosion and friction resistant; non-marking, non-toxic.
Temperature Range: -45℃ to +130℃ (bearing capacity decreases above +35℃).
3. Polyurethane Wheel (TPU)
Properties: Ground protection, vibration absorption, excellent friction, and corrosion resistance.
Temperature Range: -45℃ to +90℃ (bearing capacity decreases above +35℃).
4. Casting Polyurethane (CPU) Elastomer Wheel
lProperties: Abrasion, corrosion, UV resistant; good elasticity.
lTemperature Range: -30℃ to +70℃ (short periods up to +90℃).
5. Casting Polyurethane (CPU) Wheel
Properties: Suitable for speeds up to 16km/h.
Temperature Range: -45℃ to +90℃.
6. Casting Nylon (MC) Wheel
Properties: Low rolling resistance; superior to injection nylon.
Temperature Range: -45℃ to +130℃ (bearing capacity decreases above +35℃).
7. Foam Polyurethane (PUE) Wheel
Properties: Excellent buffering for high-strength and high-pressure applications.
8. Solid Rubber Tire
Properties: Shock absorption, impact resistance, good elasticity.
Temperature Range: -45℃ to +90℃.
9. Pneumatic Wheel
Properties: Ideal for poor ground conditions.
Temperature Range: -30℃ to +50℃.
10. Soft Rubber Wheel
Properties: Ground protection, suitable for rough conditions.
Temperature Range: -30℃ to +80℃.
11. Synthetic Rubber Wheel (TPR)
Properties: Excellent cushioning and shock absorption.
Temperature Range: -45℃ to +60℃.
12. Antistatic Synthetic Rubber Wheel (TPE)
Properties: Static resistant.
Temperature Range: -45℃ to +60℃.
13. Cast Iron Wheel
Properties: High bearing capacity, rugged.
Temperature Range: -45℃ to +500℃.
Selecting the right material ensures the best performance and longevity for your specific needs. Additionally, consider the wheel bearing for long-term rewards.
