Apiro: the modular drive gear box system

Individual applications can be implemented with the drygear® Apiro modular drive gearbox system in an extremely modular and cost-effective manner. Possible applications can be in packaging, food, medical and many other industries. Lane adjustments, pusher tasks, gearboxes with different gear ratios, slewing rings and rotary axes can be used there. The modular gearbox system can be motorised or used for manual adjustments.  
The Apiro modular system offers different gear ratios but also length variants, so that there are endless possibilities for combinations and applications.
