Product description

A modular design series supplying up to 6 million Nm

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 (to DIN 24312). This swash-plate, axial piston motor was designed with special emphasis on good starting torque. 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 oilmotor capacities are : 79, 111, 158, 216, 353 and 491 cm3.

The tried and tested "m" range, which has been used in many thousands of applications for almost 30 years, is also available. It has been constantly improved, and is dimensionally interchangeable with the "am" series.



ROLLSTAR planetary gear reducers are compact gear units providing high torques at low net weights. The most modern computing and manufacturing processes, quality assurance and generously proportioned roller bearings ensure a long service life. The ring gears are made from quenched and tempered alloy steel which is then nitrided; the planetary gears are made from high-grade, hardened carburised steel. The surfaces of the teeth are ground to ensure high load resistance and quiet gear running. All planetary carriers have two sets of bearings and three or more satellite gears which means that dimensions can be substantially reduced. Each planetary stage is available with several reductions, giving a large number of reductions for multi-step gears.

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