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 series?

The YRTS (high-speed) type features cylindrical rollers separated by a radial cage, allowing higher speeds. The standard YRT type has a full-complement arrangement without a cage, offering higher load capacity and rigidity for lower speeds.

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

The minimum order quantity is 1 set.

Q:Can this bearing be customized?

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

Q:How should the bearing be installed?

Clean components, mount using a heater or fixture without striking the rings, and tighten screws in a cross pattern at 40%, 70%, and 100% of standard torque using a torque wrench. Verify accuracy with a dial indicator.

Q:What are the lubrication requirements?

Bearings are pre-filled with grease. Do not mix different grease brands. Replenish every 6-12 months based on conditions. For oil lubrication, specify in the order form; bearings will ship with only anti-rust oil.
