Description
The MaalonDrive® Hollow 8mm - type 2 micro positioning gear is characterised, in particular, by its hollow shaft, yet with minimal outer dimensions. Optical or electrical signals can be guided through the hollow shaft on the central rotary axis of the gear, thereby allowing a simple and space-saving design to be realised. At the core of this micro gearbox is a zero-backlash MaalonDrive® gear with a reduction ratio of 120:1. The preloaded ball bearings on both the input shaft as well as the output shaft result in precise guiding and allow the application to be directly connected.
