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 applications for RB Series Crossed Roller Bearings?

They are ideal for industrial robot joints, machining center rotary tables, robotic arms, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing equipment.

Q:How does the split ring structure benefit the bearing?

The split outer ring and integral inner ring allow for adjustable clearance and preload, ensuring high-precision rotational motion and preventing roller skewing.

Q:What types of loads can these bearings withstand?

Due to the perpendicular roller arrangement on V-grooved surfaces, they can withstand significant radial, axial, and moment loads from all directions.

Q:Is customization available for these bearings?

Yes, customization options include samples, designs, full customization, minor customization, and flexible customization.

Q:What is the minimum order quantity for this product?

The minimum order quantity is 1 set.
