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 operational speeds. The standard YRT type has a full-complement arrangement without a cage, offering higher load capacity and rigidity for lower speeds.

Q:What are the common applications for YRT bearings?

They are widely used in precision equipment such as precision rotary tables, vertical grinding machines, indexing heads, gear hobbing machines, and gear milling machine work spindles.

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.

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

The minimum order quantity is 1 set.

Q:How should the bearings be lubricated?

Bearings are pre-filled with grease upon shipment. If oil lubrication is preferred, it must be specified in the order. Do not mix different brands of grease. Replenishment is recommended every six to twelve months depending on conditions.
