Key features

16g Ultra-Lightweight Design: Weighing only 16g with 15x28x7mm dimensions, it significantly reduces equipment weight while maintaining high load capacity.

Zero Maintenance Operation: Premium grease combined with double metal shields (ZZ) or rubber seals (2RS) eliminates dust ingress and prevents lubrication leaks.

ABEC-5 High Precision: Manufactured to P5/ABEC-5 tolerances to ensure smooth, low-friction rotation, extending the lifespan of your critical machinery.

Up to 30,000 RPM Speed: Optimized internal geometry and low-friction cages enable ultra-high-speed performance without dangerous overheating.

Premium GCr15 Chrome Steel: Delivers 50% higher fatigue life and superior wear resistance compared to standard carbon steel alternatives.

Versatile Motor Applications: Provides unwavering reliability for drone motors, high-speed vacuum cleaners, power tools, and robotics drivetrains.

Z3/Z4 Low Noise Level: 100% factory acoustic testing guarantees whisper-quiet operation, solving noise compliance issues for consumer electronics.

Tailored OEM/ODM Solutions: Customize clearances (C0/C3), cage materials (Nylon/Steel), and greases to perfectly match your specific working environments.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier focused on bearings and power-transmission products. It offers broad customization and ODM services, but does not provide 3D software design, SDKs, or OEM services for popular brands, and reported no new products in the past year. ISO 9001 certification is stated. The supplier claims integrated R&D-production bases, automated equipment, measurement tools, and strict quality control, while finished products are checked by packing staff. Export activity is reported at 90% of sales, with self-operated import/export rights and one year of export experience. However, reported operating revenue, costs, gross profit, and operating profit for the stated periods are zero, and there is no overseas warehouse, overseas showroom, overseas agent or branch, or offline trade-show participation. After-sales capability is not sufficiently documented.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and its business scope includes bearing manufacturing, bearing sales, and high-speed precision heavy-duty bearings. This supports classification as a specialized bearing and industrial power-transmission supplier.

CertificationsThe supplier states that it holds an ISO 9001 supplier management-system certification. The provided information does not include the certificate number, issuing body, or validity period, but it is explicit evidence of certification holding.

After-Sales capabilityThe supplier has no in-stock service capacity, overseas warehouse, overseas showroom, overseas agents or branches, and offers overseas services in zero countries. Service-capability assessment also lacks written procedures or followed records, so the available evidence does not demonstrate a robust after-sales network.

Financial creditThe stated financial records report zero operating revenue, operating costs, gross profit, and operating profit for the listed periods. These figures provide explicit negative evidence regarding reported financial performance and therefore raise a material financial-credibility concern.

Production capacityThe business scope explicitly includes bearing manufacturing, including high-speed precision heavy-duty bearings. The supplier also claims integrated R&D-production bases, automated equipment, precise measuring tools, skilled operators, and strict process quality control, although the provided information does not quantify production capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, flexible customization, and ODM services. This is direct evidence of broad product customization capability, despite the absence of 3D software design services.

Product Q&A

Q:Can I customize the 6902 thin section ball bearings for high-speed micro motors?

Yes, Welink Bearing provides full OEM/ODM services. For high-speed applications like vacuum cleaners or drones, we can customize the radial clearance (e.g., C3/C4), retainers (Nylon PA66 for high speed), and use specialized high-temperature grease to ensure optimal performance at speeds up to 30,000 RPM.

Q:What are the precision and noise levels of your 6902 deep groove ball bearings?

Our 6902 series is manufactured from premium GCr15 chrome steel, achieving ABEC-3 (P6) to ABEC-5 (P5) precision ratings. Every batch undergoes strict vibration and noise testing to meet Z3V3 or Z4V4 standards, guaranteeing silent and stable rotation for your compact machinery.

Q:What is the MOQ and standard lead time for wholesale bearing orders?

As a direct factory manufacturer, we offer a low MOQ of 1,000 pieces for standard 6902 bearings to support your trial tests. Regular orders have a rapid lead time of 7 to 15 days. We also support free samples if you provide your courier account.

Q:Is Welink Bearing a trading company or a certified manufacturer?

Welink Bearing is a verified manufacturer integrating R&D, production, and global trade. We are strictly ISO 9001:2015 certified. All our thin-section bearings come with comprehensive export documentation, including Commercial Invoices, Packing Lists, and Certificates of Compliance (COC) for seamless customs clearance.
