Our VRB series planetary gearbox comes in a wide range of frame sizes from 042 to 220, it provides two levels backlash, P0 for micro backlash rating of <<2 arcmin at 1-stage, and <<4 arcmin at 2-stage. P1 for precision backlash rating of <<4 arcmin at 1-stage and <<6 arcmin at 2-stage. With helical gearing arrangement and integrated configuration, VRB features high torsional rigidity, high precision and high torque, as well as low mass moments of inertia for highest dynamics. Its optimized mounting system allows motor to be installed in any directions. VRB is cost effective planetary gearbox with the best torque-low heat performance and an ideal solution for servo and stepper applications.
