RA crossed roller bearings are specifically designed for precision rotary systems,featuring a 90° orthogonal crossed roller layout that enables simultaneous bearing of radial loads,axial loads,and overturning moment loads.They are suitable for high-precision,high-rigidity,and space-constrained applications.Their integrated inner ring structure enhances system rigidity and simplifies installation,while the optional preload configuration eliminates internal clearances,making them ideal for equipment requiring stable and precise rotation,such as industrial robots,precision machine tools,optical instruments,and semiconductor manufacturing equipment.
Robotics refers to the engineering field and application scenarios centered on various automated mechanical devices,mainly including industrial articulated robots,collaborative robots (cobots) and robot rotary actuators.These devices rely on precise rotary joints to complete operations such as handling,assembly,testing and welding,especially the 4th,5th and 6th axes (wrist joints) of robotic arms,which need to bear complex loads while achieving micron-level positioning accuracy.Robotic equipment has extremely strict requirements for core rotating parts: compact size for limited installation space,high rigidity to reduce deformation,high precision to ensure operation accuracy,and stable performance for long-term continuous operation.
RA crossed roller bearings are the core key components of robotic joints and actuators,and their performance directly determines the motion accuracy and stability of robots.
Composite load capacity
They can simultaneously bear radial,axial and moment loads,replacing multiple bearing combinations to simplify the joint structure and reduce assembly errors,which is critical for robotic wrist joints bearing end-effector and payload loads.
Ultra-high rigidity
The crossed roller layout maximizes the contact area and reduces deformation,providing rigid support for high-torque robotic joints and ensuring no deflection during operation.
High rotation precision
With P4-level precision and run-out tolerance ≤0.002mm,they meet the nanometer-level positioning requirements of robots,ensuring accurate operation in assembly,testing and other scenarios.
Compact and space-saving
The thin-section design is highly compatible with the slim structure of robotic joints,perfectly adapting to the limited space inside collaborative robots and industrial robot actuators.
Low friction and long service life
Optimized roller end-face geometry reduces sliding friction,lowering power consumption and heat generation.The hardened material and strict manufacturing process ensure long-term stable operation of robots.
Customized adaptability
They support special lubricating greases for high-temperature or vacuum environments,non-standard dimensions and hybrid ceramic roller designs,adapting to diverse working conditions of different robots.
