Flexible actuator configuration and reinforced output bearing

HFUS Series Units are available in nine sizes with gear ratios of 30, 50, 80, 100, 120 and 160:1 offering repeatable peak torques from 9 to 1840 Nm.

Wide variety

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.

The HFUS Series is available in three versions: the HFUS-2UH Unit is fully sealed with a large hollow shaft diameter to feed through supply lines, shafts or cables for further drive systems. The HFUS-2SO and HFUS-2SH Simplicity Units are very short and lightweight, consisting of a component set and the heavy duty output bearing. The absence of input and output flanges means maximum flexibility in design integration, the 2SO version being available with a standard Wave Generator and the 2SH version with hollow shaft.

All versions of the HFUS Series are available on request for ambient temperatures -40 to 90 °C and with a wide range of special lubricants tailored for your application.
