Crossed Roller Bearing Harmonic Reducers for Robot Joint Solution
Crossed roller bearing harmonic reducers provide a more precise, stable, and compact transmission solution for robot joints through high rigidity, multi-directional load capacity, and zero-backlash design.
As robot joints continue to require higher positioning accuracy, repeatability, load capacity, and lightweight designs, traditional bearing structures face challenges in rigidity, space utilization, and motion control. Crossed roller bearing harmonic reducers integrate harmonic drive technology with crossed roller bearing technology, utilizing rollers arranged at 90-degree angles to support radial loads, axial loads, and overturning moments simultaneously. Combined with preload technology to eliminate internal clearance, they achieve high rigidity, zero backlash, and excellent repeat positioning accuracy. In addition, their compact structure helps reduce joint size, lower weight, and improve system reliability, making them widely used in humanoid robots, collaborative robots, industrial robots, and high-precision automation equipment.
