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 is the main structural difference between SX and RB series bearings?

The SX series features a two-piece split outer ring connected by three circlips, whereas the RB series is the standard model. Both have a one-piece inner ring, but the SX design is optimized for space-saving in compact applications.

Q:Does the SX series bearing have sealing rings?

No, there are no sealing rings between the inner and outer rings in the SX series crossed cylindrical roller bearing model.

Q:What are the recommended installation methods for SX series bearings?

Since the outer and inner rings do not have mounting holes, installation requires flanges and support seats. The split outer ring is connected circumferentially by three connecting rings.

Q:What types of applications are suitable for the SX series?

It is ideal for applications requiring high rotational accuracy of the inner ring, such as industrial robot joints, rotary tables on machining centers, robotic arm rotation units, and medical equipment.

Q:Is customization available for these bearings?

Yes, OEM and ODM services are available. Customization options include full customization, minor customization, and flexible customization from samples or designs.
