Key features

High Rotational Accuracy: 90-degree crossed rollers with spacers prevent friction, skewing, and locking for precise motion.

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

Multi-Directional Load Capacity: Withstands significant radial, axial, and moment loads simultaneously due to perpendicular roller arrangement.

Adjustable Clearance: Split ring structure allows clearance adjustment for high-precision rotation under preload.

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

Easy Installation: Split rings fixed together after assembly make installation straightforward and efficient.

Low Starting Torque: Nylon spacers provide low moment of inertia and easy control of angular indexing.

Wide Application Range: Ideal for industrial robots, machining centers, medical equipment, and IC manufacturing tools.

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. Overseas warehouse, showroom, agent/branch, and offline trade-show capabilities are absent. Certification holdings, verified customer cases, and sufficient...

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 structure of RB crossed roller bearings?

The RB-type bearing features a split outer ring and an integral inner ring, with rollers arranged perpendicularly at 90 degrees to each other.

Q:Can the clearance be adjusted?

Yes, due to the split structure of the inner and outer rings, clearance can be adjusted to enable high-precision rotational motion even when preload is applied.

Q:What types of loads can this bearing withstand?

It can withstand significant radial, axial, and moment loads from all directions due to the perpendicular arrangement of rollers on V-grooved surfaces.

Q:What material is used for these bearings?

They are made of carburized steel, which provides excellent impact resistance and surface wear resistance.

Q:What are the main applications for RB bearings?

They are suitable for industrial robot joints, machining center rotary tables, robotic arms, precision rotary tables, medical equipment, and IC manufacturing equipment.
