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 difference between YRT and YRTS bearings?

The YRTS high-speed type features separated cylindrical rollers in the radial section, allowing for higher operational speeds. The standard YRT type has a full-complement arrangement without a cage, suitable for higher load capacity and rigidity at lower speeds.

Q:How should the bearing be installed?

Clean components, mount using a heater or fixture, and tighten screws in three stages (40%, 70%, 100%) in a cross pattern. Do not strike the rings, and verify accuracy with a dial indicator.

Q:Is lubrication required before use?

Bearings are pre-filled with grease upon shipment. If oil lubrication is needed, specify it in the order. For stored bearings, run-in for 20-50 revolutions before operation.

Q:Can I customize the bearing specifications?

Yes, we offer OEM and ODM services including full customization from samples or designs, minor customization, and flexible customization options.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 1 set, making it easy to order samples or small batches.
