Industrial robot bearings need to adapt to harsh conditions such as high precision, high load, high-speed motion, and frequent start stop. Robot bearings mainly perform rotational motion, bearing composite loads of radial, axial, and overturning moments (such as RV reducers and harmonic reducers with matching bearings), low speed and high torque (<100 rpm), high rigidity requirements, and precise angular positioning (repeat positioning accuracy within ± 0.01mm).
