Radial piston motor performance

Since 1955, when the first radial piston high torque low speed motor was designed by STAFFA engineers, Staffa has maintained leadership in fulfilling customer needs. Today, Staffa motors have the most technically advanced design on the market. Staffa's performance and reliability is well documented with over 35 years of successful applications worldwide. Staffa motors are the choice of industry leaders to directly propel, drive, swing, or rotate heavy loads and inertias at low speeds.

All over the world, Staffa motors are used on: marine machinery (winch and steering mechanisms), plastic injection moulding machines (extruder screw drives), mining machinery (swing, track, wheel, bucket, and cutterhead drives), earthmoving and construction equipment (wheel, track, swing and implement drives) and forestry machines (swing and cutterhead drives) as well as many others.

Staffa motors offer consistent, controlled acceleration of loads and smooth, steady, low speed operation. Moving parts are immersed in hydraulic fluid, so Staffa motors do not require periodic lubrication.

They also save money by increasing usable drive power and reducing drive train maintenance.

Utilizing the only fully hydrostatically balanced design in the industry, Staffa motors wear less and have superior starting torque because there is minimal metal-to-metal contact within the motor.

A modular design concept has enabled the motor to be continuously adapted to the changing needs of our customers. This concept also allows product availability and service to be matched to market requirements.
