drygear® Apiro: robot gearbox system

Individual applications can be implemented with the drygear® Apiro modular 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.

The gearboxes and components at a glance

Robot gearbox with drive pin

Gearbox with drive pin

The standard version among the Apiro gearboxes: the gearbox with drive pin enables a direct drive connection.  Available gear ratios: 4:1, 32:1, 64:1, optionally also: 3:1, 5:1, 8:1, 16:1

Gearbox with multi-functional profile

Gearbox with multi-functional profile

With the help of the multi-functional profile, series connections of gears can be implemented, as spacings of elements or products can be regulated. This combination is often used for applications in the food or packaging industry.

Gearbox with rotary disc

Gearbox with rotary disc

This gearbox is particularly suitable for slewing ring applications, as it can be used also as a rotary axis. For example, it can be used in laboratory automation.

Gearbox with coupling

Gearbox with coupling

The coupling can be used to attach various shafts with a maximum diameter of 12 millimetres. An exemplary application is the adaptation to linear axes.

Cantilever axes

Cantilever axes

The linear gearbox enables different strokes in the application.   Rack and pinion elements included. Configurable in different lengths, for example, for sliding applications.



The drygear Apiro accessories allow different installation options for vertical, axial horizontal movements and profile stop (more information in the data sheet).

Versatile and flexible applications with modular gearboxes

For simple and complicated movements
