Your advantages

Economical operation
thanks to the wear-free SPIROPLAN® gearing and minimised friction losses.

Lightweight and compact
thanks to the aluminium housing and the specially designed gearing.

Explosion-protected worm gear units Explosion-protected bevel gearboxes

Our smallest: also light and compact in ATEX design

The special feature of the SPIROPLAN®right-angle gear units is the wear-free gearing. It ensures reliable power transmission and thus also the speed adjustment of your conveyor system. And, of course, it is also on board with the explosion-protected gear unit version: an ATEX-compliant gear unit for equipment category II2GD.

Thanks to this gearing, our SPIROPLAN®-right-angle gear units deliver output torques of up to 180 Nm in the motor power range from 0.12 kW to 3.0 kW. Their steel-steel material combination and the special meshing ratios enable the short gearbox design - for space-saving installation of the drives.

Only half the solution without a motor? Then take advantage of our sophisticated modular system and combine the explosion-protected gear units of the W series with a motor. explosion-protected motor of your choice.

The details make the difference

Thanks to the aluminium housing, these right-angle gear units are true lightweights. And thanks to the special gearing and lubrication for life, they require very little maintenance. Just right for long and reliable operation. Without compromises: because the SPIROPLAN®-right-angle gear units are suitable for almost all drive tasks thanks to their many design variants.
