SHD series Hollow Shaft Harmonic Gearbox

Features

FHTW SHD units are highly compact harmonic drive gearboxes with large hollow shaft.These series have six sizes with gear ratios of 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 12 to 453 Nm.

The output bearing with high tilting rigidity enables the direct introduction of high payloads without further support and thus permits simple and space saving design installations.

SHD-2SH harmonic gearboxes are featured by highly compact dimensions and low weight, consisting of the component set with shortened flex spline and the high capacity output bearing.The absence of input and output flanges makes maximum flexibility in design integration.The integrated hollow shaft can be used to feed through supply lines or services for further axes.The high capacity, integrated output bearing means that the unit can quickly and easily withstand heavy payloads.

SHD harmonic gearbox is mainly used in robots,metal working machines,communication equipment,crating and packaging machine,paper-making machines,optical machines,printing machine, medical equipment,bending machine,etc.
