HYDRAULIC GEAR MOTORS
 
   
 

The "am" series of axial piston hydraulic motors is our own development and was designed for a normal pressure of 250 bar and a maximum pressure of 400 bar (according to DIN 24312). This swash-plate, axial piston motor was designed with special emphasis on good start-up behaviour.

This new series is characterised by a co-axial design with a continuous hollow shaft, allowing a wide variety of accessories such as brakes, rollback stops, synchronous drives and tachometers to be fitted.

Available hydraulic motor displacements are : 79, 111, 158, 216, 353 and 491 cm3.

The tried and tested "m" range, which has been used in many thousands of applications since 1966, is also available. It has been constantly improved and is dimensionally interchangeable with the "am" series.

As delivery times become ever shorter, an increasing flexibility level is also required on behalf of hydraulic motor and gearbox suppliers. ROLLSTAR constantly fulfils these requirements for the widest possible range of applications and also has the necessary experience and references.

We would be pleased to receive your enquiry, and kindly ask you to submit the following information :

  • type of machine to be driven
  • intermittent and continuous output torque
  • continuous and intermittant rpm at input
  • type of driving motor (electrical, hydraulic, etc.)
  • flow rate of pump at operating pressure (continuous / intermittant)
  • requested ratio of gear
  • type of attachment / at input side / at output side (enclose drawing if possible)
  • environment temperature and conditions
  • -perating cycle
  • requested min. bearing life time
