Can you produce bearings from my technical drawings or samples?
Yes. We accept both technical drawings (PDF/DWG/STEP formats) and physical samples for reverse engineering. Our professional R&D team will analyze your requirements, confirm dimensional tolerances, and propose the optimal material and precision grade before production begins. This ensures the finished bearing perfectly matches your application's load, speed, and environmental conditions.
What quality certifications apply to your OEM products?
All OEM products undergo strict full-process quality monitoring and comply with international standards:
Authentic Brand Sourcing
How do you guarantee NSK and INA bearings are 100% authentic?
Authenticity is our non-negotiable commitment. Here is how we ensure it:
- We source directly from authorized distribution channels -- no gray market or parallel imports
- Every batch comes with original manufacturer documentation and traceable batch codes
- Our QC team inspects packaging integrity, laser markings, and dimensional accuracy before shipment
- Backed by our 12-month warranty -- if authenticity is disputed, we handle the claim directly
What brand bearings do you carry in ready-to-ship stock?
We maintain extensive ready-to-ship inventory of NSK and INA branded bearings across a wide range of series including deep groove ball bearings, angular contact bearings, cylindrical roller bearings, and tapered roller bearings. Standard stock items have no small order limit -- you can order as few as 1 piece. For specific model availability and real-time stock quantities, please contact us directly with your bearing model number.
Can you provide original manufacturer certificates with shipment?
Yes. We provide full documentation packages upon request, including quality inspection reports, material certificates, and where applicable, original brand certificates of conformity. For OEM products, we also supply our own ISO 9001:2015 inspection reports. Please specify your documentation requirements when placing your inquiry so we can prepare everything before shipment.
MOQ, Samples & Delivery
What is the minimum order quantity (MOQ)?
Our standard MOQ is 1 piece for both stock bearings and sample orders -- no minimum commitment required to start a business relationship. For OEM/ODM custom production runs, the MOQ may vary depending on bearing type and complexity; our team will confirm this during the technical review stage. We believe flexibility at the start builds long-term partnerships.
How do I get free samples? What is the sample policy?
We offer free samples to qualified distributors and buyers. Here is how it works:
- ✓ Sample cost: Free of charge (product value waived for qualified buyers)
- ✓ Freight: Buyer is responsible for shipping costs (express courier)
- ✓ Lead time: 3-5 business days from confirmation
- ✓ No small order limit: Sample quantities have no minimum restriction
How long does bulk order production and delivery take?
Note: Lead times are calculated from payment confirmation. Rush orders may be accommodated -- contact us to discuss your timeline.
What shipping methods do you use for international orders?
We ship worldwide and serve buyers across Europe, North America, Southeast Asia, and the Middle East. Available shipping options include:
- Express courier (DHL / FedEx / UPS) -- recommended for samples and urgent small orders
- Sea freight -- cost-effective for large bulk orders
- Air freight -- balanced speed and cost for medium-volume urgent orders
We provide full tracking numbers and shipment documentation (commercial invoice, packing list, certificate of origin) for all orders.
Payment & After-Sales
What payment methods do you accept?
We accept three payment methods to accommodate buyers globally:
What does the 12-month warranty cover?
Our 12-month after-sales warranty covers manufacturing defects, material quality issues, and performance failures under normal operating conditions. Our support includes:
- Professional technical guidance for installation and application optimization
- Failure analysis and root cause investigation by our R&D team
- Replacement or refund for confirmed quality defects
- Long-term cooperation support with stable pricing and reliable supply chain
Will pricing remain stable for long-term orders?
We operate on a principle of integrity and stable pricing. While raw material market fluctuations may occasionally affect costs, we commit to transparent communication well in advance of any price adjustments. For long-term partners, we work to lock in pricing agreements and ensure supply chain continuity. Our goal is to build sustainable cooperation, not short-term transactions.
