Our 4 stage planetary gearbox (series N4) features a heavy duty bearing on low-shaft. We have designed it to bear enormous radial load. Thanks to our R&D team who have made it easier for us to develop a 4 stage planetary gearbox with proportionate distribution of torque.

Every SGR 4 stage planetary gearbox is case hardened to guarantee transmission efficiency. Moreover, they come with rigid and nodular cast iron casing, making them durable and reliable even in the adverse working environment.

As a planetary drive manufacturer, apart from the high and reliable performance, load capacity and low speed shaft bearing; all our 4 stage planetary gearboxes produce virtually no noise.

Also, with vast experience on how planetary gearbox works, we are able to attain a wide range of output speeds and torques. You can use a planetary gear ratio formula to determine the best 4 stage planetary gearbox, suitable for your unique applications.

At SGR, you can find customized designs alongside our standard 4 stage planetary gearboxes.
