PMG

Small, economical gearbox

PMG Series compact gearboxes are available in four sizes with gear ratios of 50, 72, 80, 88, 100 and 110: 1 offering repeatable peak torques from 0.3 to 14.7 Nm.

The PMG Series is available in two versions: the PMG M Gearbox with input hub for motor adaptation and the PMG S Gearbox with input shaft. Both variants come with on output shaft.

If required, the Gearboxes can be tailored to your application and can be Easily mounted directly to standard servo motors. Zero backlash Means short cycle times and high accuracy.
