Regardless of size, each model delivers:- High Starting Torque: Typically this is in the 92-94% range. That means overall hydraulic systems savings because designers can use smaller motors. Higher starting torque also means increased vehicle gradeability and more drawbar pull.
- High Running Torque: Friction loss and viscous drag at high speed are both lower due to the internal rolling contact seal elements. Large flow passages reduce internal pressure drop. Typical breakaway pressure at a no load condition is less than 10 PSI.
- More Useable Speed: Smooth running at low speed (less than 10 RPM) with minimal performance loss at high speeds (up to 3,500 RPM). Smooth performance over an unusually wide speed range. Low speed characteristics often eliminate the need for additional speed reduction.
- Long Life: Performance stays relatively constant over the motor’s working life. The internal rolling seal elements are essentially frictionless and wear compensating. The rolling seal element design also tolerates a high degree of contamination so the motors perform well in free-wheeling applications.

The positive contact provided by rolling seals between rotor and housing and between abutments and seal plates creates relatively frictionless operation that makes these motors relatively insensitive to wear over their exceedingly long working life.
