The 300 series is compact and powerful. Their planetary drivetrains make them ideal for all heavy-duty applications where impact loads and impact ratios are more important. With a wide range of options for mounting, gear layout, output shaft and motor interfaces, the product configuration is very generic. All features are available in each of 20 fine-spaced frame sizes with a torque range of 1,000 to 1,100,000 Nm.
