Due to the compact design of the planetary gearbox you achieve a high gear ratio in a limited space. This gives the gearbox a low weight compared to other types of gearboxes with the same gear ratio.
BJ-Gear A/S works with several manufacturers of planetary gearboxes. A planetary gearbox can obtain a high torque compared to the size of the gearbox, and due to the compact design of the gearbox you achieve a high gear ratio in a limited space. This gives the gearbox a low weight compared to other types of gearboxes with the same gear ratio.
Because of the structure of the planetary gearboxes they are able to withstand high radial and axial loads. Furthermore, the design has the advantage that several gears share the load between them, which gives the gearbox a high efficiency and a longer service life. As an integral part of the solution, the planetary gearbox is adapted to your specific needs. This means that the input shaft and motor flange are adapted to fit your engine specifically.
The planetary gearboxes are an obvious choice for positioning tasks, solutions with a servo motor, and other solutions where precision is important. The planetary gearboxes are available as right angle planetary gearboxes. We also offer solutions where planetary gearboxes are mounted with our own worm gearboxes, helical gearboxes or as first step in our actuators.
We offer planetary gearboxes with the following specifications
- Gear ratio: 3:1 to 200:1.
- 1, 2 or 3 steps.
- Output torque: From 9 to 2,000 Nm.
- Backlach: Available for precision gearboxes down to 1 arc min.
High efficiency and long service life
The gears in a planetary gearbox are often subjected to a smaller load than other types of gearboxes. Because there are several contact surfaces between the different components of the gear, a larger area can distribute the weight evenly around the shaft. Thus, the load is divided between several gears. This gives the planetary gearbox a high efficiency, makes the gearbox resistant to damage at a higher torque, and gives the gearbox a longer life span in general.

Planetary gearheads - output shaft
BJ-Gear A/S offers planetary gearboxes with output shaft, which have a precision gear design and a professional gear processing that create a low backlash operation, high efficiency, smooth running, low noise and long life of the planetary gearboxes.
Planetary gearheads - right angle
The right angle planetary gearboxes offered by BJ-Gear A/S has a design that is suitable for combination operation with servo motor high-speed input while drastically reducing the installation space. The right angle gearboxes are ideal for achieving maximum output torque.
Planetary gearheads - output flange
The planetary gearboxes with output flange have a design that is suitable for combination operation with servo motor high-speed input. The gearboxes are ideal for achieving maximum output torque, and their hollow output shaft connects perfectly with circular flanges and reduces the installation space.
Planetary gearheads - stainless steel
The stainless steel planetary gearboxes with output shaft are precision inline servo gearboxes with smooth appearance and permanent laser engraved labels that provide outstanding corrosion resistance in washdown environments. The stainless steel planetary gearboxes are developed and constructed for use in industries such as food, pharmaceutical, chemical biotechnology, aerospace, anti-magnetic applications and environments that require corrosion protection.
