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 dimensioned roller bearings ensure a long service life. The crown gears are made of quenched and tempered steel alloy and nitrided, the planetary gears are made of high-grade, hardened carburised steel. The surfaces of the teeth are ground to ensure high load resistance and quiet operation of the gears. All planetary carriers have a dual bearing and three or more planetary gears which means that dimensions can be substantially reduced. Each planetary gear stage is available with several reductions, giving a large number of different reductions for multi-stage gears.

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...
