Planetary Gearboxes P Series

Planetary gearbox with stationary housing and rotating output shaft

The PULS planetary gearboxes are a modular gearbox series in the torque range from 1,000 Nm to 1,000,000 Nm. Thanks to the modular design, the planetary gearboxes are available in a wide range of versions and can therefore cover a wide variety of application areas. PULS planetary gearboxes are used in a variety of industries, e.g. general mechanical engineering, construction machinery, machine tools, renewable energy, special-purpose vehicle engineering, mining, recycling, custom machine engineering, test rig engineering and many more.

If for some reason requirements of the gearbox cannot be covered by our modular system, there is always the possibility or making minor or more substantive customer-specific modifications. Custom gearboxes are also built in exceptional cases.

PULSGETRIEBE has been manufacturing modular planetary gearboxes since the 1960s and has continuously refined and expanded the model series in the intervening decades. The planetary gearboxes shown here are based on the latest technology in conjunction with decades of experience. In terms of power density and durability, they have been optimized over the past 5 years, always with a view to ensuring dimensional compatibility with older versions so that existing applications can easily be outfitted with more powerful gearboxes.
