Series 51: A Family of Bent Axis Motors to Meet Today's Market Requirements

The SAUER-SUNDSTRAND Series 51 Variable Displacement motors were designed to be the most technically advanced hydraulic units in the industry. They are intended to be primarily integrated into a closed circuit hydraulic system for the purpose of transfer and control of hydraulic power. The motors, also, are used in open circuit applications. The Series 51 is a Bent Axis Design and provides features that are advantageous to creating compact hydraulic systems that are cost efficient for a broad range of torque and speed capability. The controls included in the large array of control options were designed to meet the requirements of the worldwide Markets for the 1990's Hydraulic Power Transmissions.
