YMSY SERIES

The YMSY series motors adapts an advanced GEROLOR gear set designed with disc distribution flow and high pressure.

This motor series uses the “ROLOR” gear type manufactured with most advanced technology and quality available to provide low pressure start up, smooth reliable operation and high efficiency.

The output shaft tapered roller bearings allow for high axial and radial forces.

Advanced design in disc distribution fl ow,which can automatically compensate in operating with high volume efficiency and long life.

The YMSY series has the same dimensions and mounting data as the YMS series.This series is rated 10-20% higher for higher torque and higher pressure applications.

Distribution Type: Disc Distribution
Model: YMSY
Displacement: [in/rev] [4.88~22.88]        cm/rev 80~415
Max Operating Pressure: PSI = 3263   MPa = 22.5
Speed Range: RPM = 30~800
Max. Output Power: [HP] [32]    Kw = 24

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 free wheeling 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 filter 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.
