What are the payment terms?

Accepted payment terms include LC, T/T, D/P, PayPal, Western Union, and Small-amount payment.

What is the lead time for production?

The average lead time is 1-3 months, varying slightly between peak and off-season periods.

How should the bearing be installed?

Installation requires controlled tightening torque using a torque wrench in a cross pattern (40%, 70%, 100%). Force must not be applied directly to rolling elements, and dimensions should be verified with calipers and dial indicators.

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 models?

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

Q:What lubrication options are available?

Bearings are typically pre-filled with grease. Customers can specify custom grease requirements or opt for oil lubrication. Different grease brands must not be mixed to prevent failure.

Q:What is the Minimum Order Quantity (MOQ)?

The Minimum Order Quantity is 1 set, making it suitable for sampling and small orders.

Q:Is customization available for this bearing?

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

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.
