Efficient, compact, versatile
Hollow shaft gearboxes from Ruhrgetriebe
Maximum power transmission with minimal space requirements – discover our high-performance hollow shaft gearboxes for versatile applications.
About us
Manufacturer of efficient geared motors
Space-saving installation
Hollow shaft gearboxes allow direct mounting on shafts without the need for additional couplings or adapters. This saves space and simplifies installation, which is particularly beneficial in tight machine rooms.
Efficient power transmission
The direct form-fit connection between the drive shaft and gearbox reduces energy loss, enhancing efficiency. Fewer components also result in smoother operation and reduced wear.
Flexibility in application
Thanks to the hollow shaft, various shaft types can be directly inserted and secured, for example, with a keyway connection. This simplifies integration into existing systems and increases application possibilities.

Hollow shaft gearboxes from the expert for worm geared motors
In the worm gear sector, we convince through many years of technical experience, field-tested expertise and our outstanding manufacturing quality. Our product range includes worm gear units in various designs: single or two-stage with output shaft or hollow shaft. You also have the choice between different types of electric motor. We offer geared motors with hollow shafts for three-phase, direct or alternating current. Hollow shaft gearboxes are used in areas where low weight is required or the shaft must have a high natural frequency. Furthermore, it is possible that the cavity is required for other components, axles, etc.

What are hollow shaft gearboxes?
Why a hollow shaft gearbox?
Hollow shaft gearboxes offer numerous advantages over traditional solid shaft gearboxes. With their compact design and direct shaft mounting, they are ideal for applications that require efficient, space-saving, and reliable power transmission.
Space-saving installation
Hollow shaft gearboxes are directly mounted onto the drive shaft, eliminating the need for additional couplings or adapters. This not only saves space but also reduces installation effort. Additionally, it minimizes potential alignment errors that can occur with traditional coupling systems.
Low wear and tear
The direct power transmission results in lower friction losses, enhancing energy efficiency. At the same time, wear is reduced as fewer moving parts are required. This leads to a longer gearbox lifespan and lower maintenance costs.
Versatile application
Thanks to their flexible design, hollow shaft gearboxes can be integrated into a wide range of machines and applications. They are suitable for use in conveyor systems, mechanical engineering, agricultural technology, and many other fields.
Reduced maintenance
By eliminating additional couplings or fastening elements, there are fewer wear parts that need to be maintained or replaced. This results in longer maintenance intervals and increased operational reliability for your systems.
Easy customization
Our hollow shaft gearboxes are compatible with various shaft diameters and can be adapted with keyway connections or other fastening methods as needed. This keeps your drive system flexible and easily integrable into existing machines.
High torque transmission
The direct connection to the drive shaft allows the gearbox to efficiently transmit high torque without the need for additional components such as couplings or intermediate bearings. This enables the implementation of powerful drive solutions even in space-constrained applications.
Gear motor with hollow shaft or solid shaft?
Solid shafts and hollow shafts basically work in exactly the opposite direction. Whereas with a hollow shaft gearbox the application must be provided with a shaft and is inserted into the gearbox, a solid shaft turns from the inside, so to speak, as it is itself an integral part of the solid shaft gearbox. Solid shafts can be provided with radial or axial threaded holes, which serves for fastening. A geared motor with a hollow shaft, on the other hand, is more commonly used in connection with weight-reduced designs. Hollow shaft gearboxes are also the first choice when the shaft must have a high natural frequency. The required cavity may also be necessary for other components, axles.
Have any questions? Here are the answers!
