Ultramite Gear Drives

Falk Ultramite Concentric Inline Gear Drives are built for longer service life. An integral high-speed pinion is fully supported by bearings within the gearbox, not by motor bearings, while dual lip seals prevent contamination.


Ultramite is motor-independent allowing the use of standard NEMA C-face or IEC motors. The innovative motor bushing eliminates fretting between the motor and the gear drive. This design offers easy installation and allows for quick, trouble-free change out, even after years of hard, continuous use. 


Multiple mounting positions are available, including base, wall, top, vertical, shaft and flange. Falk Ultramite Gearmotors have continuous-duty ratings from the American Gear Manufacturers Association (AGMA).
