FAQ
Q: What is the minimum order quantity? Can I order samples first?
A: Our standard MOQ is 100 pieces per model. Sample orders are welcome — you can order 1–2 pieces for testing before placing a bulk order.
Q: Can I customize the wheel color or bracket finish?
A: Yes! We offer full OEM/ODM customization. You can choose custom wheel colors, bracket finishes, and even branded packaging with your logo. Custom orders have their own MOQ — contact us for details.
Q: Will these casters scratch or leave marks on my floors?
A: Not at all. Our PA wheels are non-marking and floor-friendly. They roll smoothly and quietly on tile, concrete, vinyl, and other hard surfaces without leaving scuffs or stains.
Q: These have a top plate — how do I install them on my equipment?
A: Simply bolt the top plate onto the equipment base using the pre-drilled mounting holes. Bolt spacing and hole diameters are clearly marked in the spec table above. Use M8–10 bolts (depending on model size) — no special tools needed.
Q: How do I know this caster can handle my equipment's weight?
A: Each caster supports up to 350 kg individually. For a 4-caster setup, the total safe working load is around 1225 kg (safety margin included). Always distribute weight evenly across all casters. If you're unsure, our team can help you pick the right model.
Q: What is the typical lead time for orders?
A: Sample orders ship within 3–5 business days. Standard bulk orders typically take 15–25 days, depending on quantity. Custom orders may take a bit longer — we'll confirm the exact timeline when you order.
