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 transmission ratios are: 4:1, 32:1, 64:1, and optionally also: 3:1, 5:1, 8:1, 16:1
