PSN The helical precision planetary gearbox for low-noise operation and high bearing loads Our PSN embodies pure progress: Its innovative helical teeth safeguard low-noise operations. This precision planetary gearbox minimizes vibrations, and therefore increases the quality of your workpiece surfaces even under the highest bearing loads. Nominal output torque Radial force Axial force Torsional backlash Protection class Frame sizes
