Series EPN5: 5 Stage Planetary Gearbox

Our 5-stage planetary gearbox (EPN5 series) is a high-precision, high-quality motion control device that complies with ISO 9001:2008, SGS, and CE standards. You can choose from our wide range of EPN series gearboxes to suit your industrial application needs.
All of our in-line 5-stage planetary gearboxes have a male and female configuration. Reasons for its flexibility and adaptability. Each planetary gearbox is designed to withstand strong radial and axial loads on the output shaft.
We are the only supplier of inline planetary gearboxes with a modular design. It enables us to produce custom designs for all clients’ specific needs.
In addition, with rigid and heavy-duty bearings, we can achieve the required efficiency of planetary gearboxes; and achieve proportional torque distribution. In addition, each 5-stage planetary gearbox is case hardened for reliability and extended service life.
We’ll help you choose the best design to optimize your operation with a wide range of output speeds and torques. You don’t have to go through the tedious process of using a planetary gear calculator.
