Description
3-stage planetary gearboxes (EPN3 series) are available in a wide range of low-speed shaft designs, such as cylindrical shafts with keys, splined shafts, hollow shafts with shrink disc, or splined hollow shafts.
Each three-stage planetary gearbox has a high capacity output bearing. Therefore, all our 3-stage planetary gearboxes guarantee high axial and radial capacity. In addition, they resist tilting moments, thereby increasing the reliability and efficiency of the transmission.
Be a quality-conscious planetary gearbox manufacturer; all our 3-stage planetary gearboxes have tooth profiles precision machined to ensure low noise operation.
We will machine it to your specifications if you need a flange, foot, or shaft mounting solution. Likewise, each gearbox part goes through a rigorous quality inspection before being shipped.
Using the planetary gear calculator, you can choose from various speed and torque outputs. Our 3-stage planetary gearboxes have a modular design for easy customization.
In addition, each 3-stage planetary gearbox has solid and stable support. This ensures a high torsional rigidity for each gearbox.
