Frequently Asked Questions

What materials are your bearings made from?

Our standard bearings are manufactured from GCr15 chrome steel, known for high hardness, wear resistance, and fatigue strength. Stainless steel (SS304/SS316) options are available for corrosion-resistant applications.

Do you offer OEM/ODM services?

Yes, we provide full OEM and ODM support including custom branding, packaging, and engineering modifications to meet your specifications.

What is the difference between ZZ and 2RS bearings?

ZZ indicates metal shields on both sides, offering protection from dust with low friction. 2RS means rubber seals on both sides, providing better protection against moisture and contaminants but with slightly higher torque.

What is your minimum order quantity (MOQ)?

Our standard MOQ is 1,000 pieces per model, but we can accommodate smaller trial orders. Contact us for sample availability.

How do I place an order?

You can contact us directly via email or through our official website. We respond to all inquiries within 24 hours.
