Helical worm gearboxes

Series H

The worm reduction gears come in two series: X and H.



The series X
, featuring a worm and worm wheel set, is available in versions XA with shaft and XF-XC with mounting provisions for motor.

Version XF (bell housing + coupling) offers great versatility to suit a broad range of applications and provides higher efficiency than the compact line XC, where the emphasis is on space efficiency.



Series H offers the same features as series X with an added plus: a spur gear pre-stage at the input end provides higher performance and a broader range of ratios than the X series.

Frame sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy steel and ground-finished.



The worm wheel has a cast iron hub with cast bronze insert. Hollow output shaft is supplied as standard.

Broad range of options available: second input, output flange, single or double extension output shaft, torque limiter with through cable, torque arm.
