How is the quality of the bearings ensured?

We use a three-dimensional coordinate measuring machine to collect coordinate data and generate detailed test reports covering measurement values, tolerance ranges, and deviation values.

AI-Powered supplier vetting

SummaryFRT Group is a limited company with 106 employees, operating in CNC machine tools, bearings, and non-standard machinery parts. It reports 18 years of machinery-industry experience, dedicated design, production, assembly, and sales teams, production equipment, testing instruments, and a quality assurance system. The supplier supports extensive customization, has introduced new products during the past year, provides ODM services, and supplies OEM services to recognized brands. Quality processes include documented inspection, complaint handling, traceability, and corrective-action procedures. Overseas support covers installation, training, repair, maintenance, and debugging. However, the supplied information identifies no valid manufacturing contract with related subcontractors, no overseas warehouse or showroom, and no available SDK. Financial information is limited to reporting years rather than financial performance indicators. Evidence of specific customer cases and formal certifications is not provided.

Supplier typeThe supplier is identified as a limited company and a combined business, with 106 employees. Its stated product scope includes CNC machine tools, bearings, and non-standard machinery parts, while its broader business scope covers mechanical equipment and related industrial products.

After-Sales capabilityThe supplier provides overseas equipment installation, training, repair, maintenance, and debugging, and maintains documented procedures for complaint handling. It also reports a quality assurance system and corrective-action records, although it has no overseas warehouse or showroom.

R&D capabilityThe supplier reports that it introduced new products during the past year, has experienced mechanical design teams, and provides ODM services. It does not have an available SDK, but that limitation does not negate the documented product-development and design capabilities.

Production capacityProduction capability is supported by CNC and numerical-control equipment, dedicated production and processing teams, testing instruments, inventory capability, 60 qualified service-capability suppliers, and documented supplier-management procedures. The absence of a valid contract with related subcontractors is a stated control weakness, while no overseas warehouse or showroom is available.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are reported consistently across the R&D and design-service information.

Client casesThe supplier states that it provides OEM services for recognized brands, which is evidence of brand-customer experience. However, no customer names, project details, product examples, or independently verifiable case descriptions are provided.

Product Q&A

Q:What is the MOQ and lead time?

Standard stock items have an MOQ of 1 pc with a lead time of 1-7 days. Custom or P4 high precision orders require 15-30 working days.

Q:What are the common failures of cross roller bearings?

Common issues include abnormal noise (insufficient grease/improper mounting), sticky rotation (over preload/bad flatness), and increased clearance (shock overload). A rigid mounting seat is required.

Q:What are the typical applications for RU cross roller bearings?

Typical applications include robot joints, optical inspection turntables, CCD vision equipment, small CNC index tables, semiconductor equipment, medical devices, and automated rotary fixtures.

Q:Do you provide drawings, 3D files, and inspection reports?

We provide 2D drawings for standard models and partial items with 3D STEP files. An inspection report can be supplied together with the shipment.

Q:Are there specific requirements for the mounting housing?

Yes, the bearing is sensitive to housing deformation. Good flatness and high rigidity of the mounting base are mandatory. Poor rigidity will destroy rotary accuracy.
