AI-Powered supplier vetting

SummaryLuoyang Rock Precision Engineering Co., Ltd. is a China-based limited company established in 2022 with 19 employees. Its stated product scope includes bearings, machine tools, robots, and port machinery, and its products are reportedly used in construction machinery, mining equipment, CNC machine tools, wind power, robotics, and heavy industry. The supplier reports flexible customization and OEM service for well-known brands, but no SDK availability. Manufacturing resources include one production line and two export-trade staff, with one experienced export employee. Service-control weaknesses are documented: no written procedures or records for supplier-service assessment, corrective and preventive actions, or complaint handling. Finished products are checked by packing staff, and continuous quantity reconciliation is not performed for each batch.

After-Sales capabilityFinished products are checked by packing staff, but the supplier has no written procedures or records for effective service-capability assessment, corrective and preventive actions, or customer-complaint handling. It also has no overseas warehouse, showroom, agent or branch, and has not participated in offline trade shows, indicating limited documented and overseas service infrastructure.

R&D capabilityThe company describes 20 years of continuous innovation and modern precision technology, and its products are used in technically demanding sectors including CNC machine tools, wind power, robotics, and heavy industry. However, it explicitly reports no available SDK, so software-development integration capability is not demonstrated.

Production capacityThe supplier reports one manufacturing production line and one year of export experience, supported by two export-trade staff and one experienced export employee. It does not perform continuous quantity reconciliation for every batch or mass-production run, which is a stated production-control weakness.

Customization capabilityThe supplier explicitly reports customization from samples, designs, full customization, minor customization, and flexible customization. It also states that it provides OEM services for well-known brands, supporting a positive assessment of customization capability.

Product Q&A

Q:What are the main advantages of the XSU series over the XU series?

The XSU series features double-sided spring plate seals and a more compact overall dimension profile, making it better suited for applications with limited installation space.

Q:Can the XSU bearings be used for both inner and outer ring rotation?

Yes, depending on accuracy requirements, they can be configured for either inner ring or outer ring rotation, providing considerable design flexibility.

Q:Do I need fixing flanges or bearing seats for installation?

No, the XSU series comes with pre-machined mounting holes, eliminating the need for fixing flanges and support seats, which significantly simplifies the assembly process.

Q:What type of loads can these crossed roller bearings withstand?

They are designed to withstand combined loads, including radial, axial, and overturning moments, due to the 90-degree crossed arrangement of the cylindrical rollers.

Q:Are the inner and outer rings separable?

No, the XSU series features an integral structure for both inner and outer rings, meaning they are unseparated.
