Reduction Drives for Aviation

We are experts in aviation mechanics. We manufacture and offer a big range of PSRU's transforming ordinary car and motorcycle engine into an aircraft engine. Our PSRU's are of the highest quality and used by aircraft homebuilders in Poland and other countries.
We offer also (car) engines adapted for aviation aims.

Belt Reduction Drives

Belt Reduction Drives

 

Belts  we use have been specially developed for highly loaded, high speed drives. Those high strength  belts, reinforced with aramid fibers, feature maximum load carrying capacity and long service life. 

Woven fabric facing reduces friction, wear and noise. Belt absorbs surge and shock loading, and reduces problems such as resonance and vibration associated with propeller aerodynamic excitation. Maintenance free operation with no lubrication or retensioning required.
