To select the right caster, you need to consider:

• Load capacity
• Floor condition
• Working environment
• Frequency of movement

👉 Most buyers get this wrong by focusing only on size.

To ensure safety and long-term durability, we recommend using the “N-1” Rule. This accounts for uneven floors or weight shifts where only three wheels may be supporting the full load at once.

The Formula:

• T = Required Load Capacity per Caster

• W = Weight of the cart/equipment

• M = Maximum payload weight

• N = Number of casters (typically 4)

Example:

If your cart weighs 100kg and carries a 500kg load using 4 casters:

Result: You should choose casters with a minimum capacity of 200kg each.

We provide:

• PU wheels – quiet, durable, floor-friendly
• PP wheels – lightweight, resistant to chemicals
• Rubber wheels – shock-absorbing, good for rough floors
• Nylon wheels – high load, low rolling resistance
• Steel / Cast iron wheels – extreme heavy-duty
• High-temperature wheels – for ovens and industrial use

• Smooth floors → PU or nylon
• Rough floors → Rubber
• Heavy loads → Nylon or steel
• Sensitive floors → PU

👉 Wrong material = short lifespan + customer complaints

Yes — with the right configuration:

• Weather-resistant materials
• Anti-rust treatment
• Larger wheel diameter

👉 Outdoor use requires different specs — don’t use indoor models.

We don’t rely on “good samples” — we ensure batch consistency:

• Raw material inspection
• Load testing per batch
• Rotation & durability testing
• Final QC before shipment

👉 What you test is what you get.

Yes, including:

• Load capacity test
• Material specs
• Internal QC reports

Depends on:

• Load
• Usage frequency
• Floor condition

👉 With correct selection, our casters are designed for long-term industrial use.
