Pallet stacker wheels can be made from various materials, each with its own advantages and disadvantages depending on the operating environment, floor condition, load capacity, and cost considerations. Here's an overview of the most common materials used:
1. Polyurethane (PU) Wheels
Advantages:
- Quiet operation
- Non-marking (won't leave stains on floors)
- Resistant to chemicals, oils, and abrasion
- Provides good grip and shock absorption
- Durable on smooth surfaces
Disadvantages:
- Can wear out quickly on rough or uneven surfaces
- Less resistant to high temperatures
- Slightly higher cost compared to rubber
2. Nylon Wheels
Advantages:
- Extremely hard and durable
- Low rolling resistance (easy to roll)
- Excellent load-bearing capacity
- Resistant to most chemicals
Disadvantages:
- Noisy on hard surfaces
- Slippery when wet
- Can damage delicate floors (may scratch or mark)
- Poor shock absorption
3. Rubber Wheels
Advantages:
- Very quiet and smooth operation
- Good grip and shock absorption
- Protects floors well
- Suitable for uneven or rough terrain
Disadvantages:
- Lower load capacity than nylon or polyurethane
- Higher rolling resistance (harder to push or pull)
- Prone to wear over time, especially with heavy loads
- Can leave marks on some floors
4. Steel or Cast Iron Wheels
Advantages:
- Extremely high load capacity
- Very durable and long-lasting
- Ideal for harsh environments or heavy-duty industrial use
Disadvantages:
- Very noisy
- Can severely damage floors
- No shock absorption
- High risk of slipping on wet surfaces
5. Phenolic Resin Wheels
Advantages:
- High load capacity
- Resistant to oil, grease, and some chemicals
- Non-marking
- Affordable compared to steel or polyurethane
Disadvantages:
- Brittle (can chip or crack)
- Poor shock absorption
- Can damage floors over time
Choosing the Right Material
Condition and Recommended Material
| Smooth indoor floors | Polyurethane or Nylon |
| Uneven or outdoor surfaces | Rubber or Steel |
| Heavy industrial loads | Steel or Phenolic Resin |
| Noise-sensitive areas | Rubber or Polyurethane |
| Cost-sensitive applications| Nylon or Phenolic Resin |
