Key features

40,000 RPM High Speed Capacity: Precision-engineered raceways and optimal grease fill allow continuous, stable operation at up to 40,000 RPM for micro motors.

Effective Dust Isolation: The high-quality RS/2RS rubber seals effectively prevent dust and moisture ingress, ensuring maintenance-free longevity in demanding environments.

Flawless 3D Printing & Robotics: Minimal friction and strictly controlled Z3/Z4 low-noise grades guarantee smooth, jitter-free movement for precision instruments.

Superior Fatigue Resistance: Manufactured from premium GCr15 Chrome Steel, providing exceptional dynamic load capacity (Cr: 1.08 kN), far outlasting standard carbon alternatives.

Zero Clearance Guesswork: Factory-set C0/C3 radial internal clearance ensures perfect thermal expansion management, stopping premature bearing lock-up at high speeds.

Smooth & Stable Rotation: Equipped with a lightweight, high-strength SPCC steel ribbon cage to minimize vibration and centrifugal stress during ultra-fast rotation.

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 is the difference between 686RS and 686ZZ miniature deep groove ball bearings?

The 686RS (or 686-2RS) features rubber seals for superior dust and water resistance, ideal for exposed environments like RC cars or drones. The 686ZZ uses metal shields, offering less friction and slightly higher top speeds (up to 43,000 RPM), which is perfect for clean, enclosed applications like 3D printers.

Q:Do you offer the 6mm micro bearing in stainless steel for food-grade or medical applications?

Yes! In addition to standard GCr15 Chrome Steel, Welink Bearing manufactures the 686 series in 440C Stainless Steel. This provides excellent corrosion resistance for medical instruments and food processing equipment. All our materials are ISO 9001, RoHS, and REACH certified.

Q:Can I request customized ABEC-5 precision 686-2RS bearings for high-speed UAV motors?

Absolutely. We specialize in OEM customization for industrial clients. We can supply 686RS bearings with strictly controlled ABEC-5 tolerances, optimized C3 clearance, and specific high-speed synthetic grease tailored for UAV, drone, and micro-motor applications.
