Are these bearings suitable for pure radial loads?

No, they are not suitable for pure radial load conditions. For high-speed and heavy-load scenarios, they should be combined with other bearings like deep groove ball bearings.

What is the limit speed rating?

Both single and double-direction types have a medium limit rotational speed, suitable for non-high-speed equipment operation.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company whose stated scope includes bearing sales and manufacturing. It presents claims of high-end bearing development, R&D investment, automated production, full-process quality control, clean workshops, heat treatment, testing, and ISO9001, DIN, and ABMA-related certifications. However, several operational controls are undocumented: no written procedures or records for supplier assessment, corrective and preventive actions, or complaint handling; no raw-material traceability; no inventory, overseas warehouse, overseas showroom, overseas agent or branch capability; and no offline trade-show participation. The supplier states service terms and lead times within 15 workdays, but financial information reports zero revenue, costs, profits, cash flows, and current ratio for the stated periods, which does not establish financial strength. Customization is mentioned, while specific customization capacity is not demonstrated. Export activity to over 50 countries is...

Supplier typeThe supplier is explicitly classified as a Trading Company. Its stated business scope covers bearing sales, sales of specialized bearings and transmission components, and bearing manufacturing, indicating a trading-led business with manufacturing included in its registered scope.

CertificationsThe supplier states that professional testing and certifications including ISO9001, DIN, and ABMA confirm its quality control. This is explicit evidence of claimed certification-related credentials, although the slices do not provide certificate numbers, validity dates, or issuing-body verification.

After-Sales capabilityThe company description states that it provides after-sales services through a multilingual team and logistics partners. However, no written complaint-handling procedures or records are reported, so the existence of a service offering is supported while the effectiveness and formal management of after-sales support remain weakly documented.

Financial creditThe reported financial indicators show zero operating revenue, costs, profits, cash received, cash inflows, cash outflows, and current ratio for the stated periods. These figures do not demonstrate financial strength or operating scale, although the slices do not explain whether the zeros reflect unavailable, incomplete, or actual financial data.

R&D capabilityThe supplier explicitly describes technological innovation as a core focus, increased R&D investment, and a professional team developing high-performance bearings. These statements support an innovation commitment, but no quantitative R&D results, patents, or specific developed products are provided.

Production capacityThe supplier claims manufacturing in its business scope and describes clean workshops, advanced automatic production equipment, heat treatment, professional testing, and full-process quality control. Nevertheless, it reports no in-stock capacity and lacks raw-material traceability, while outsourcing procedures and manufacturing-capacity contracts are unknown; production capability is therefore supported by stated facilities and processes but has important control gaps.

Customization capabilityThe company states that it provides customization services and links its offering to professional teams, R&D investment, and high-end bearing development. The slices do not specify customization equipment, engineering workflow, minimum quantities, or examples of customized products, so the capability is claimed but only partially evidenced.

Product Q&A

Q:How does your factory control quality?

All bearing parts before and during production undergo 100% strict inspection, including crack detection, roundness, hardness, roughness, and geometry size. All bearings meet ISO international standards.

Q:What materials are available for the bearings?

We offer chrome steel GCR15, stainless steel, ceramics, and other materials.

Q:How long is the delivery time?

If goods are in stock, delivery takes 5 to 10 days. If out of stock, it takes 15 to 20 days, depending on the quantity.

Q:Do you accept OEM and custom orders?

Yes, we accept OEM and can customize products according to your samples or drawings.

Q:What are the load capacity features?

Single-direction types handle high one-way axial loads with minor radial resistance. Double-direction types support dual axial loads for stable bidirectional positioning.
