The YMSJ series motors incorporates the advanced GEROLOR gear set with 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 speed and pressure.

The series has many sizes and options to make it very flexible for many applications
Distribution Type: Disc. Distribution
Model: YMSJ
Displacement: [in3./rev] [4.88 ~ 22.88], cm3/rev. 80 ~ 375
Max.Operating Pressure: [PSI] [3263], MPa 22.5
Speed Range: RPM 30 ~ 800
Max. Output Power: [HP] [27], Kw 20
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 housings for corrosive environments and applications.
For optimum results the following working conditions are recommended:
*        Oil temperature should be between 20o - 60o C [68o - 180o F]
*        Oil filter of 10 - 20 micron
*        Oil viscosity 42 - 74 mm2 at 40o C
*         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.
