Series N4: 4-Stage Planetary Gearbox
Our planetary gearboxes with four stages (N4 series) are fitted with high-performance bearings on the shaft that are low. The gearbox was designed to stand up to enormous circular loads. We are grateful for our R&D team, they made it possible for us to create a four-stage gearbox planetary with an equal distribution of torque.
Each planetary gearbox has four stages and is fully case-hardened for reliable transmission. Furthermore, they have strong steel housing made of ductile iron for long-term durability and dependability even in extreme operating conditions.
As a maker of gearboxes for planetary use, we also have access to high-quality performance capacity, load carrying capacity, and shaft bearings with low speeds Our 4-stage gearboxes for planetary are almost quiet.
Furthermore, due to our extensive experience with the workings of planetary gearboxes, they can achieve a variety of torques and output speeds. It is possible to use the formula for planetary gear ratio to identify the ideal 4-stage planetary gearbox for your specific needs.
At our company, you can get custom designs and our standard four-stage gearboxes for planetary applications.
