RB Series Cross Roller Bearings

The distinctive feature of the RB Series Cross Roller Bearings is the cross-arranged rollers inside. This unique configuration enables the bearing to bear large radial, axial loads and overturning moments simultaneously. With numerous contact points between the rollers and the raceway and uniform force distribution, the load-bearing capacity is greatly enhanced.

Cross Roller Structure：The distinctive feature of the RB Series Cross Roller Bearings is the cross-arranged rollers inside. This unique configuration enables the bearing to bear large radial, axial loads and overturning moments simultaneously. With numerous contact points between the rollers and the raceway and uniform force distribution, the load-bearing capacity is greatly enhanced.
Precision Machined Components：The rollers are made of high-quality steel and finely ground, with a smooth surface and extremely high dimensional accuracy, fitting closely with the raceway to effectively reduce friction and adapt to high-speed operation. The inner and outer rings are forged from high-strength alloys and have gone through multiple precision machining processes, such as turning, grinding and heat treatment, possessing excellent round 度，cylindric 度 and surface hardness, providing solid support for the rollers.
Compact Design：The overall structure is compact, achieving powerful functions within a limited space. It is suitable for equipment with strict installation space requirements, saving space while ensuring performance.

Superior Combined Load-bearing：Thanks to the special structure, it has outstanding load-bearing capacities for radial, axial and overturning moments. It is commonly used in key parts that require multi-directional force support, such as industrial robot joints, precision rotary tables and medical devices.
High Precision Positioning：The precise cooperation of all components ensures extremely high rotational and positioning accuracy, meeting the stringent precision requirements of precision instruments and high-end equipment manufacturing and facilitating high-precision operations.
Stable Operation：It operates with small vibration and low noise. Even under high-speed and heavy-load working conditions, it can maintain stable operation, improving the reliability and service life of the equipment.

Application

The bearings can be used in the following industries

Industrial Automation：It is an indispensable part of the rotating joints of industrial robots and automated production lines, ensuring the flexible and precise movement of moving parts, improving production efficiency and product quality.
Precision Instruments：Used in precision rotary tables of astronomical telescopes and measuring instruments, it provides stable support for high-precision observation and measurement, promoting the progress of scientific research and detection work.
Medical Equipment：In medical devices such as surgical robots and high-end imaging equipment, it meets the requirements of precision control, ensuring the precision and safety of the medical process.
