Char-Lynn Hydraulic Motors from Buyers Products are designed to be economical, efficient, compact, and powerful. They are a great solution for powering medium-duty applications like compressors, augers, winches, cranes, and spreaders. The motors have an industry-proven spool valve design combined with state-of-the-art gerotors. They excel at jobs that need a high degree of start-up torque or just the right mixture of torque and flow rate. Choose from a wide range of motors depending on your needs for flow rates, torque, and starting torque. Each model is available with either a 2-bolt or 4-bolt mount. The last digit of the part number (2 or 4) will indicate the number of bolts.
