FAQ

Q: How do l choose the right casters for my equipment?
A:Selecting the right caster involves considering several key factors.
(1)Load Capacity:Calculate the load each caster needs to bear (total weight divided by the number of casters, incorporating a safety factor of 1.2-1.5).
(2)Operating Environment: Indoor/outdoor? Floor type (epoxy, tile, carpet, rough concrete)? Exposure to oil, water, chemicals, or extreme temperatures?
(3)Functional Needs: Do you need fixed ,swivel , swivel wheel braking or total braking, Requirements for noise reduction, anti-static properties, or stem guards?
(4)Mounting Type: Plate mount (bolt holes), threaded stem, grip ring stem, expanding adapter, etc.
(5)Wheel Material: Choose based on environment and load-e.g., PP/PA polyurethane (PU), PVC ,rubber, TPR, or cast iron .
Q: What is the difference between nylon, polyurethane(PU), and rubber wheels? How do I choose?
A:Nylon Wheels (PP/PA):High hardness, excellent load capacity,(wear-resistant), and resistant to many chemicals. Can be noisy and may mark floors. Ideal for heavy-duty industrial use on rough surfaces.
Polyurethane Wheels (PU):Excellent elasticity, high load capacity, extremely (wear-resistant), super quiet, and very floor-friendly(non-marking). The premium choice for many industrial applications, but often higher cost.
Rubber/TPR Wheels: Good shock absorption, quiet operation, and floor-friendly. Generally have a lower load capacity and can be de- graded by oil and chemicals. Best for light-medium duty, office furniture, and medical equipment.
Q: What do "Dynamic Load" and "Static Load" mean for casters?
A:Dynamic Load: The maximum weight a caster can safely bear while in motion
Static Load: The maximum weight a caster can support when the equipment is stationary
Static load ratings are always significantly higher than dynamic load ratings. Always base your selection on the dynamic load capacity.

Q: Can you provide special casters for high-temperature, chemical-resistant, or anti-static applications?

A: Yes, we offer a range of specialty casters:
High-Temp: Features high-temperature grease, heat-resistant wheels (e.g., phenolic), and sometimes metal wheels.
Chemical-Resistant: wheels made from specific compounds like Vulkollan or EPDM rubber, and stainless steel or plastic swivel assem- blies.
Anti-Static/Conductive: Wheels with carbon additives to dissipate static electricity, crucial for electronics manufacturing and explo-
sive environments.
Q: What are the different types of brakes? A: Common brake types include:
Total Brake / Dual Brake:Locks both the wheel's rotation and the swivel movement. Wheel Brake: Only locks the wheel, allowing the caster to swivel.
Swivel Lock / Directional Lock:Only locks the swivel, allowing the wheel to roll straight. Step-On Brake: Activated by foot pressure
Q: What is your typical production lead time?
A:For standard products, the lead time is typically 3-7days after order confirmation. For large custom orders, the lead time will be con- firmed based on the project's complexity and quantity.

Q: What quality control processes do you have in place?

A: We implement a rigorous QC system that includes:
Incoming Inspection:Checking raw materials.
In-Process Inspection (IPQC):Monitoring production stages (stamping, welding, heat treatment, assembly).
Final Random Inspection(FRI):Testing finished products for load capacity, rotation, brake function, and appearance against agreed standards
Load Testing: We perform destructive and non-destructive load tests on samples from each batch.

Q: Can you produce custom casters according to our drawings or samples?
A: Absolutely. We are an OEM/ODM manufacturer with strong R&D and tooling capabilities. We can develop custom solutions based on your specifications, samples, or drawings.

Q: What materials are used for the top plate and swivel mechanism? 

A: The housing is typically made from:
Pressed Steel: Most common, cost-effective, and strong. Often zinc-plated for corrosion resistance.
Stainless Steel (e.g., SS304/SS316): For corrosive, humid, or cleanroom environments (food, medical, chemical). Nylon/Plastic: Lightweight and completely corrosion-proof for light-duty applications.

Q: What type of bearings do you use in the wheel and swivel?

A:Bearing choice depends on the caster series and application:
Wheel Bearings: Roller bearings (for heavy loads), ball bearings (for smooth medium-duty movement), or plain bushings (for light du- ty/low cost).
Swivel Bearings: Double ball races or precision ball bearings for smooth rotation and reduced swivel force.
Q: What is your Minimum Order Quantity (MOQ)?
A: For standard items, our MOQ can be as low as 100-500 pcs per model/specification. For custom-designed products, the MOQ will be higher to cover tooling costs. We are flexible and can discuss solutions for smaller trial orders.

Q: Can you provide samples? Are they free?
A: Yes, we can provide samples for quality verification. Samples are usually provided for a charge, which is refundable if a subsequent order is placed. Freight costs are typically borne by the customer.
Q: What are your payment terms?

A: Common terms include:
T/T(Wire Transfer): 30-50% deposit, balance before shipment or against copy of B/L. Payment terms for established customers may be negotiable.
Q: What certifcations do your products have?
A: Our products are certified to meet international standards such as DIN ISO 9001 for quality management. Our casters can be tested and certified to meet specific performance . We can also provide compliance certificates for materials like RoHS and REACH.

Q: How do you handle packaging and shipping?
A: We use standard export-grade packaging: individual poly bags, inner cartons, and strong master cartons on pallets. We can ship by sea (FCL/LCL), air, or express courier (DHL, FedEx, etc.). We work with reliable freight forwarders but can also ship based on your instruc- tions.
