Description

Series EPN4: 4 Stage Planetary Gearbox

Our 4-stage planetary gearboxes (EPN4 series) are equipped with heavy-duty bearings on the low shaft. We designed it to withstand huge radial loads. Thanks to our R&D team, they made it easier for us to develop a 4-stage planetary gearbox with proportional torque distribution.
Each 4-stage planetary gearbox is case hardened for transmission efficiency. Additionally, they feature rigid and ductile iron housings that remain durable and reliable even in harsh operating environments.
As a planetary drive manufacturer, in addition to high performance, reliable load carrying capacity, and low-speed shaft bearings, all our 4-stage planetary gearboxes produce virtually no noise.
Furthermore, with our extensive experience in planetary gearboxes, we can obtain various output speeds and torques. You can use the planetary gear ratio formula to determine your unique application’s best 4-stage planetary gearbox.
You can find custom designs alongside our standard 4-stage planetary gearboxes.
