Key features

The extremely narrow profile (30x37x4mm) minimizes installation space and weight, delivering high performance for compact robot joints, rotary encoders, and drone gimbals.

Engineered with high-grade steel balls and optimized raceways to reduce friction torque by 35%, ensuring buttery-smooth rotation and higher motor energy efficiency.

Stop experiencing system jitter or clicking noise; our 100% automated acoustic testing guarantees silent, ultra-stable running in sensitive optical instruments.

Manufactured with top-tier vacuum-degassed chrome steel for exceptional wear resistance and structural integrity, lowering long-term maintenance overhead.

Delivers significantly tighter dimensional and radial runout controls than standard ABEC-1 bearings, guaranteeing unmatched repeatability for automation devices.

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:What makes the 6706 thin section bearing ideal for robotic joints?

The 6706 bearing (30x37x4mm) features an extremely thin cross-section and a large 30mm bore. This unique design allows robotic designers to route cables, wiring, and pneumatic lines directly through the center of a hollow shaft, saving critical space while maintaining lightweight and smooth rotational capabilities.

Q:Is the 6706 ball bearing suitable for heavy-load industrial equipment?

No, the 6706-ZZ is a thin section ball bearing engineered for light to moderate radial loads in high-speed, compact applications. If your project demands heavy load capacities (e.g., industrial roller shutters or heavy gearboxes), we recommend our standard metric series (like 6200 or 6300 series). Please contact Welink Bearing's engineering team for custom high-capacity solutions.

Q:How does Welink Bearing guarantee the quality and runout of the 6706 series?

As a professional factory, Welink Bearing enforces strict ISO9001:2015 quality control. Every single batch of 6706 bearings undergoes 100% automated acoustic inspection for noise and vibration (Z3V3 standard), dimensional accuracy (tolerances controlled to ABEC-5/P5), and custom radial clearance checks.

Q:How do I choose between 6706-ZZ (metal shielded) and 6706-2RS (rubber sealed)?

The 6706-ZZ features metal shields on both sides, providing low friction and high speed limits, perfect for clean, closed environments. The 6706-2RS has rubber contact seals, which offer superior protection against dust and moisture in harsh conditions but introduce slightly higher rotational resistance. Both versions come pre-lubricated with high-performance grease.
