Key features

With precise 20x27x4mm dimensions, our 6704 bearing minimizes installation footprint and reduces overall equipment weight, perfectly tailored for compact power tools and rotary encoders.

Engineered for up to 18,000 RPM (grease), it delivers exceptionally low frictional torque, which can help extend your motor's battery life and overall efficiency compared to standard bearings.

Eliminate operational humming; our Z3/Z4 vibration-rated bearings crafted with premium GCr15 steel ensure silent, jitter-free performance, critical for sensitive optical imaging and medical 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 materials and dimensions define your 6704 thin section ball bearings?

Our 6704 deep groove ball bearings feature precise 20x27x4mm dimensions. To ensure maximum wear resistance and lifespan, they are manufactured using premium GCr15 chrome steel or high-grade stainless steel, making them highly durable for high-speed applications.

Q:How does the 6704 bearing perform in power tools and optical devices?

The 6704 is engineered for low friction and rapid rotation, safely reaching up to 18,000 RPM with grease lubrication. Coupled with stringent Z3V3/Z4V4 noise and vibration ratings, it guarantees the smooth, silent, and stable operation required for precision optical imaging and professional power tools.

Q:Can Welink Bearing customize the 6704 bearings and handle international shipping?

Absolutely. As a direct manufacturer in Fujian, China, we provide robust OEM/ODM services including custom seals (ZZ, 2RS), specific clearances (C2, C3), and tailored packaging. We export globally with secure industrial packing and provide full documentation (Commercial Invoice, Packing List, BL, COC) for smooth customs clearance.
