The new NTP – Qualified for more Value

The new NTP planetary gearbox with output flange uses the familiar output geometry of the TP+ gearbox. The reinforced roller bearings on the output allow very high external forces. Coupled with the new toothing and the backlash of ≤ 5 arcmin, the NTP offers unique performance parameters for this product segment. 

Thanks to a wide range of ratios, the NTP planetary gearbox is suitable for the most diverse applications. 

The new NTP planetary gearbox

Benefits for your application

Improved repeat accuracy

With backlash ≤ 5 arcmin, the new toothing class of the product allows it to be used in applications requiring increased levels of precision.

Greater absorption of external forces

The use of more powerful roller bearings allows the NTP to absorb significantly higher external forces.


Better synchronization

The new, high-quality toothing components with revised microgeometry improve the synchronization properties of the NTP.

Reduced operating noise

As well as offering improved synchronization, the optimized toothing also has a positive impact on the operating noise of the NTP.
