3 The series motor incorporates the advanced GEROLOR gear set which reduces internal friction to a minimum. A DISC VALVE distribution system which is internally balanced to reduce friction, leakage and permit better speed control. Producing efficiency, smoother rotation, higher speed and pressure. This series has many sizes and options to make it very flexible for many applications. The output shaft is mounted on tapered rollor bearings for high radial and axial loads for very high duty applications. SPECIFICATIONS Distribution Type Model Displacement Max.

These motors are not for high speed or low pressure applications. Free Wheeling: Special Motors: These motors are created for applications where free wheeling is required or could be beneficial to the best results of the application and life of the motors and other components. These motors have special options like nickel plated shafts or housings for corrosive environments and applications. APPLICATION GUIDELINES: For optimum results the following working conditions are recommended: * Oil temperature should be between 2 o 6 o C [68 o 18 o F] * Oil filter of 1 2 micron * Oil viscosity mm 2 at 4 o C * Different shafts are used when there is a radial load or not. Check data pages * For longer life we suggest the motor at start up, run for a shorter period of time (one hour) at no more than 3% of rated speed and pressure. 118
