Key features

Engineered for ultra-smooth rotation with radial runout controlled within 0.005mm, eliminating 3D printer ghosting and axis wobble to ensure flawless, high-resolution print quality.
Stop noisy operation; our optimized raceways and specialized synthetic grease reduce vibration decibels by 85% compared to standard bearings, creating a whisper-quiet operating environment.
Premium heat-treated material ensures exceptional wear resistance and extends machinery lifespan by up to 2x under continuous-duty cycles in micro-gearboxes and servo motors.

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:How does Welink Bearing guarantee the high precision of 624zz bearings for 3D printers?
A:
At Welink Bearing, our 624zz miniature bearings are manufactured using fully automated grinding and assembly lines in our China factory. Every batch strictly achieves ABEC-5 (P5) grade with Z3V3 vibration-noise control, which ensures extremely smooth filament extrusion and stable, wobble-free movement for precision 3D printers.
Q:Can you customize the internal clearance and lubrication of 4x13x5mm (624) bearings?
A:
Yes. As a professional bearing manufacturer based in Fujian, China, we provide specialized OEM customization. We can adjust the radial play (C2, C0, or C3) and apply customized high-speed or high-temperature synthetic grease to match the specific speed requirements (up to 43,000 RPM) of your gearboxes or micro motors.
Q:What is the MOQ and delivery lead time for Welink 624 deep groove ball bearings?
A:
We maintain a consistent stock of standard 624ZZ bearings, allowing us to ship standard orders in 3 to 7 days. For large-volume OEM production, our lead time is typically 15 to 20 days. We also offer free samples for performance, speed, and vibration testing before you place a bulk order.
