About the technology

Introducing the state-of-the-art Rotrex traction drive technology: The benefits include unique compactness, efficiency, low noise and reliability.

The traction drive transmit power through friction forces between its rolling elements. As a result, low noise is achieved even at very high speeds compared traditional geared transmissions. 

The Rotrex patented traction drive uses an elastic annulus. A small pre-span is securing contact between the roller planets and the sun shaft. The patented “ramp effect” increases efficiency and reliability in the transmission. As a result, the torque transfer capability is regulated on demand through self-adjusting planet geometry. 

To enhance performance, the Rotrex traction drive uses a special traction fluid. Developed specially for its use in Rotrex superchargers, the traction fluid momentarily increases viscosity under high surface pressure. In other words, securing the optimum friction between rolling elements is key to the traction drive performance. in addition, the traction drive is kept cool and protected by the fluids capability to lubricate bearings. In conclusion, these unique performance advantages is a direct result of advances in synthetic hydrocarbon oil and grease technology. 

This traction drive combined with the latest technology in centrifugal compression, characterized by high adiabatic efficiency and low noise, gives Rotrex superchargers an exceptional competitive edge over any other forced induction solution. See our products for internal combustion solutions at
