Series EPN: Inline Planetary Gearbox

In-line planetary gearboxes (EPN series) feature rigid and precise ductile iron housings. With low noise and a high-quality manufacturing process (ISO 9001:2008, SGS and CE certified), each in-line planetary gearbox (EPNE series) is specially designed for heavy-duty applications. They can withstand strong radial or axial loads on the output shaft.
Our unique planetary operating principle allows these gearboxes to withstand high radial loads due to proportional torque distribution. Additionally, each in-line planetary gearbox (NE series) is available in female and male configurations.
Furthermore, with all our in-line planetary gearboxes (EPNE series) you can achieve different gear reduction ratios (at least 1 to 5) and output speeds. Therefore, you can adjust each in-line planetary gear to meet your manufacturing needs and requirements.
