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 advantage of the CRBH series over the RB type?

The CRBH series features a one-piece structure for both inner and outer rings, offering higher structural rigidity compared to the split outer ring of the RB type.

Q:Does the CRBH bearing require custom housings or flanges?

No, the integrated structure eliminates the need for custom housings. However, fixation via flanges and support seats is still required during installation.

Q:What are the typical applications for this bearing?

It is widely used in industrial robot joints, machining center rotary tables, robotic arm parts, medical instruments, measuring equipment, and IC manufacturing devices.

Q:Can the CRBH bearing rotate both the inner and outer rings?

Yes, the CRBH series is designed for the rotation of both the outer and inner rings.

Q:Is the CRBH bearing self-aligning?

No, it has a rigid design without a self-aligning feature (Spherical: No).
