YMT Series Quick Reference
The YMT 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 permits better speed control producing higher efficiency, smoother rotation, higher speeds and pressure. This series has many sizes and options to make it very flexible for many applications. The output shaft is mounted on tapered roller bearings for high radial and axial loads for very high duty applications. Distribution Type: Disc Distribution Model: YMT Displacement: [in3./rev] [9.77~48.82], cm3/rev. 160 ~ 800 Max. Operating Pressure: [PSI] , MPa 24 Speed Range: RPM 30~705 Max. Output Power: [HP] , Kw 35 Shaft Seals: Standard high pressure shaft seals permit applications in series or without drain line when required Low Speed Valving: These motors are manufactured following strict procedures to reduce tolerances between all components to permit lower speed, higher efficiency and smoother rotation at very low speeds. These motors are not for high speed or low pressure applications. Free Wheeling: These motors are created for applications where freewheeling is required or could be beneficial to the best results of the application and life of the motors and other components. Special Motors: 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 20o - 60o C [68o - 180o F] * Oil fi lter of 10 - 20 micron * Oil viscosity 42 - 74 mm2 at 40o 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 30% of rated speed and pressure.
