ROLLSTAR, founded in 1966, was the first provider of hydraulic motors and planetary gears from the same manufacturer in 1968. This led to the term "Hydro-Getriebemotor". Rollstar has always been synonymous with: compact dimensions, short delivery times due to modular construction, customized drive solutions, high quality, and prompt service worldwide.
Hydraulic motors and planetary gears are produced in modular construction on state-of-the-art machines in series and in large quantities for torque ranges from 1,500 Nm to 6,500,000 Nm. Additionally, there are a large number of design variants for the input and output sides, allowing for solutions to nearly all application cases. Special requests are processed promptly by the CAD-supported design office and executed on time by a flexible manufacturing process that encompasses the entire production workflow in-house. A substantial inventory allows for short delivery times when needed. Standard spare parts are therefore available within 72 hours at any international airport.
The motor features good starting and low-speed performance and has a high mechanical efficiency across the entire speed range. The output is delivered...
Upon request and as needed, bevel gearboxes and/or special gearboxes can also be manufactured! Do not hesitate to let us know your special requirement...
The torque is generated directly at the drive shaft, eliminating losses from eccentric, conical, or cam discs, among others. This results in a high me...
They are modular in design, and practically every size is available with various gear reductions. This results in almost endless combinations to achie...
These planetary gears, which can only be switched in stationary mode, are available in two- or three-stage versions. The shifting is done via a hydrau...
