Key features

High Rotational Accuracy: 90-degree perpendicular roller arrangement with spacers prevents friction and skewing for precise motion.

Multi-Direction Load Capacity: Withstands significant radial, axial, and moment loads simultaneously due to V-grooved contact surfaces.

Ultra-Thin Compact Design: Minimized inner and outer ring dimensions save installation space while maintaining high rigidity.

Split Ring Structure: Separable outer and integral inner rings allow clearance adjustment and simplified installation.

Carburized Steel Material: Provides excellent impact resistance and surface wear resistance for long service life.

High Speed Capability: Nylon spacers reduce moment of inertia and starting torque for easy angular indexing control.

Optimized Preload System: Ensures great stiffness and high roller guidance accuracy even under preload conditions.

Flexible Customization: Offers full, minor, and flexible customization options from samples or designs.

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 these bearings?

Ideal for industrial robot joints, machining center rotary tables, robotic arm rotations, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing equipment.

Q:How does the split ring design benefit installation?

The split outer ring allows the inner and outer rings to be fixed together after assembling rollers and spacers, making installation exceptionally straightforward.

Q:What types of loads can this bearing withstand?

It can withstand significant radial loads, axial loads, and moment loads from all directions due to the perpendicular roller arrangement.

Q:What material is used for the rollers and rings?

The bearings are made of carburized steel, which offers excellent impact resistance and surface wear resistance.

Q:Is customization available for this product?

Yes, we offer full customization, minor customization, and flexible customization options based on samples or designs.
