What payment terms do you accept?

We accept T/T (Bank Transfer) and Western Union. For regular orders, we usually work with a 30% deposit and the remaining 70% balance paid before shipment.

How do I choose the right seal type (ZZ / 2RS / Open)?

Open: No seals, suitable for environments with continuous lubrication (e.g., gearboxes). ZZ (Metal Shields): High speed and low friction, ideal for clean, dry environments. 2RS (Rubber Seals): Best protection against dust and moisture, perfect for outdoor or harsh environments.

Product Q&A

Q:How can I ensure the quality of your bearings?

We have a strict quality control process. Every batch of bearings undergoes noise, vibration, and precision testing before shipment. We can also provide material certificates and inspection reports upon request.

Q:Do you offer free samples?

Yes, we provide free samples (usually 1-2 pcs) for most standard models so you can test the quality. The buyer is responsible for the express shipping cost.

Q:Do you support OEM or customized branding?

Absolutely. We can laser your logo on the bearing rings and customize the packaging (color boxes/tubes) according to your brand design. This is a great way to build your local market presence.

Q:What is your Minimum Order Quantity (MOQ)?

For Standard Stock Items: No strict MOQ, even small quantities are accepted. For Customized Products: Depending on the size and complexity, please contact us for specific details.

Q:What are your shipping methods and delivery times?

Small Orders: We recommend Express (DHL, FedEx, UPS, TNT) for fast door-to-door delivery (approx. 5-7 days). Bulk Orders: We offer Sea, Air, or Railway shipping to save costs. Lead Time: Stock items ship within 3-5 days; production orders usually take 15-30 days.
