Key features

Maintenance-Free ZZ Shielded Design: Stop worrying about frequent re-lubrication and dust ingress the double metal shield seals in grease and blocks contaminants and extending service intervals.

High Load Capacity Design: Reinforced raceway geometry and optimized ball complement increase the dynamic load rating, enabling stable operation under heavy-duty conditions such as elevator pulleys

Multiple Precision Grades (P0/P6/P5): Choose the tolerance class that matches your equipment's rotational accuracy, P5-grade delivers tighter radial runout than standard P0.

Long Life, High Speed, Low Noise Performance: Optimized internal geometry and high-quality bearing steel balls enable smooth high-speed rotation with reduced vibration and noise.

Standard 25*52*15mm Interchangeable Dimensions: Fully compliant with industry-standard 6205 series envelope dimensions for drop-in replacement without redesign or retrofit costs.

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 a 6205 ZZ bearing used for?

The 6205 ZZ deep groove ball bearing is commonly used in elevator pulleys, electric motors, pumps, power tools, and medical equipment, thanks to its high load capacity and low-maintenance double-shielded design.

Q:What do the dimensions of a 6205 bearing mean?

A standard 6205 bearing has a 25mm bore diameter, 52mm outer diameter, and 15mm width, dimensions shared across all 6205-series bearings regardless of brand.

Q:What does "ZZ" mean in a bearing model number?

"ZZ" indicates the bearing has double metal shields on both sides, which retain internal grease and block dust or moisture from entering, reducing the need for maintenance.

Q:What precision grades does this bearing come in?

This bearing is available in P0 (standard), P6, and P5 tolerance classes, allowing you to select the accuracy level suited to your equipment's rotational requirements.

Q:Is this bearing maintenance-free?

Yes. The ZZ double-shielded design comes pre-lubricated and sealed, eliminating the need for regular re-greasing under normal operating conditions.
