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 main specifications of 629RS bearing?
A:
The 629RS bearing features 9mm bore diameter, 26mm outer diameter, and 8mm width. It's made from premium chrome steel SAE-52100 with pressed steel cage, double rubber seals (2RS), and offers a limiting speed of 20,000-30,000 RPM. The dynamic load rating is 4.57KN and static load is 1.98KN, making it ideal for small motors and precision instruments.
Q:What is the difference between 629RS, 629ZZ, and 629-2RS bearings?
A:
629RS and 629-2RS both feature double rubber seals providing superior protection against dust and moisture. 629ZZ uses metal shields instead of rubber seals. Rubber seals (RS) offer better contamination protection but slightly lower speed capability compared to metal shields (ZZ). All three have the same dimensions: 9x26x8mm.
Q:What applications are suitable for 629RS miniature bearing?
A:
629RS bearings are widely used in small electric motors, precision instruments, robotics, automation equipment, medical devices, dental handpieces, 3D printers, fan motors, computer cooling fans, RC models, and various electronic devices where compact size and high-speed performance are required.
Q:What precision grades are available for 629RS bearing?
A:
We offer 629RS bearings in multiple precision grades: ABEC-1 (ISO P0) as standard, with optional upgrades to ABEC-3 (P6), ABEC-5 (P5), and higher. We also provide various noise levels from Z1 to Zv4 to meet different application requirements.
Q:Do you provide certifications for 629RS bearings?
A:
Yes, Welink Bearing is ISO 9001:2015 certified manufacturer. Our 629RS bearings comply with international standards and come with CE certification and RoHS compliance. We can provide material certificates, inspection reports, and other documentation as required for your quality assurance.
