Precise. Compact. Versatile.
Planetary gearboxes from Framo Morat
Our planetary gearboxes transform high-speed rotation into precise, high-torque motion. What all models have in common: They are equipped with ground helical gears, full-needle roller bearings, and a one-piece solid planetary carrier. This ensures maximum smoothness of operation and exceptionally low noise levels in every application. In addition, all of our planetary gearboxes are protected to IP65 due to an extra shaft seal, making them resistant to water and dust ingress.
To make it as easy as possible for you to find the right planetary gearbox for your needs, we offer seven product lines with different design priorities. If your requirements go beyond our modular system, we will be more than happy to develop and manufacture a fully customized solution for you.
What application do you need our planetary gearboxes for?
Planetary gearbox series from Framo Morat
Our product range consists of seven standard product lines, each with its own design priorities and configuration. They are divided into high-end gearboxes, which offer maximum precision, and high-end economy gearboxes, which deliver excellent cost-effectiveness and short delivery times. Many models from our standard series are available from stock or can be delivered at short notice in appropriate quantities.
Within each product line, you can choose the number of gear stages, gear ratios, backlash specifications, and housing sizes. The achievable output and acceleration torques for the planetary gearbox are determined by these parameters.

Which of our standard planetary gearboxes is the right drive for your application?
Custom configurations tailored to your technical and economic requirements
Custom-engineered planetary gearboxes
Are you looking for a planetary gearbox that precisely fits your specific application? With our wide range of gearing types, materials, bearings, lubricants, and sizes, we can tailor the performance of your planetary gearbox to your specific requirements and design priorities.
Since we have experience with both metal and plastic gearings, we can also provide hybrid planetary gearboxes with high-performance plastic gear components. We typically manufacture fast-rotating gear stages from plastic and slow-rotating, heavily loaded stages from steel components. This enables us to develop exceptionally lightweight and quiet planetary gearboxes for your application.
The planetary gearbox is our starting point, but not the limit of our development expertise. We also take on the development of complete custom-engineered drive systems where planetary stages are just one part of a comprehensive solution. Our long-standing collaboration with TKE in developing curved stairlifts effectively demonstrates our capabilities.
One of the most important characteristics of a planetary gearbox is cost. That’s why we always approach custom design as an economic task – while always applying the old engineering rule of thumb “Not as good as possible, but as good as is necessary!”
Benefit from our expertise in gearing technology, our know-how in combining proven materials, and our decades of experience developing custom drive solutions!
Which application would you like us to develop your planetary gearbox for?
Precise. Dynamic. Compact.
Modular linear systems for automation and manufacturing
Modular linear systems are used whenever there are requirements for high positioning accuracy and high motion dynamics: such as in industrial 3D printing and laser cutting machines, automated production lines, and pick-and-place applications in electronics manufacturing.
Framo Morat's high-precision linear systems consist of a high-end GSD planetary gearbox, a high-precision helical pinion, and a high-precision rack. This system design enables us to achieve exceptional positioning accuracy with tolerances of less than 1 µm and highly dynamic process speeds of up to 300 m/min.
Depending on the application, the planetary gearbox can be combined with a matching pinion and corresponding rack in the required size. If the application requires it, the drive unit can also be equipped with an automatic lubrication system.

How can we ensure precise positioning for your application?
Possible applications for planetary gearboxes
Metalworking
Laser cutting machines, press brakes, CNC machining centers, and many other machine tools place high demands on motion control and dynamics. With their low backlash, planetary gearboxes from Framo Morat enable permanently precise positioning. They also support high input speeds, enabling rapid start/stop motions and high accelerations, which are essential in automated processes.
Robotics
Gear solutions for humanoid robots are increasingly taking on tasks originally intended for humans, such as logistics or assembly assistance. This requires high-precision, high-performance drive components that enable delicate movements in minimal installation space. Custom-engineered planetary gearboxes from Framo Morat deliver outstanding performance in larger joints such as the hip or knee, combining high torque density with low weight to enable dynamic and precise joint movements.
Mechanical engineering
Framo Morat's planetary gearboxes are used in various applications In mechanical engineering. In industrial cleaning systems, they enable automatic height adjustment. This increases usability as well as long-term operational efficiency – offering a clear advantage over previous manual solutions. In rotary tables with high precision requirements, high-end angular gearboxes are used primarily due to their design, exceptional performance, and high input speeds.
Intralogistics
Automated guided vehicles (AGVs) distribute goods between production lines, warehouses, and shipping areas. Autonomous logistics robots typically operate on a constant basis and transport large loads. Planetary gears from Framo Morat enable powerful drives to be implemented in the smallest spaces. They can handle high axial and radial forces and ensure smooth, efficient power transmission, even during frequent direction changes.
Conveyor technology
In conveyor rollers and drum motors for belt conveyors, planetary gearboxes are the preferred choice for drives. To create comfortable working conditions around conveyor systems, the design prioritizes minimizing noise generation. In the context of custom development, we achieve this by using plastic planetary gears.
Medical technology
Drives in surgical robots, operating tables, and imaging systems must meet the needs of two target groups: Surgeons expect high positioning accuracy, while patients appreciate low operating noise. Planetary gearboxes from Framo Morat satisfy both expectations – thanks to their minimal backlash and ground helical gears.
