Key features

Featuring a precision thin-section profile, the 6905ZZ bearing significantly saves installation space and reduces overall equipment weight without compromising radial load capacity.

Equipped with premium dual metal shields (ZZ), it effectively prevents dust ingress and retains high-quality grease while maintaining virtually zero friction for ultra-high-speed operations.

Forged from robust GCr15 Chrome Steel and engineered to strict ABEC-3 tolerances, reducing rotational vibration by 20% and ensuring long-lasting, stable performance in continuous-duty 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:What are the dimensions and key characteristics of the 6905ZZ bearing?

The standard dimensions are 25mm (inner diameter) x 42mm (outer diameter) x 9mm (width). Belonging to the 69 series, it is a "thin-section" deep groove ball bearing. Its key characteristic is providing excellent radial support while taking up minimal space, making it ideal for compact designs like robotics and small motors.

Q:Why choose the ZZ metal shield over 2RS rubber seals for this bearing?

ZZ metal shields offer non-contact protection. This means they effectively block larger particles and retain lubrication without creating physical friction against the inner ring. As a result, the 6905ZZ can achieve much higher rotational speeds (up to ~15,000 RPM) and better heat dissipation compared to contact rubber seals (2RS).

Q:Can Welink Bearing provide custom modifications for the 6905 series?

As a direct manufacturer, we offer flexible OEM/ODM services. Depending on your application, we can supply the 6905 bearing with specific clearances (like C3 for heat expansion), fill it with food-grade grease for food machinery, or upgrade the precision to ABEC-5 for sensitive instruments.
