- flow-optimized control cheek
- well balanced
- stable connecting rod
- extended intake control angle
- available with 57mm (std) and 60mm stroke
- trunnion: 20mm (except PX200, 57mm stroke: 22mm)
The width of the sealing surface on the rotary vane cheek is 15.8mm wide as on the original PX125/150 shaft.The PX200 version has here 16,8mm
The extended inlet control angle results in a larger time cross section and allows a significant increase in power over the whole speed band.
Very nice stable shaft which provides more bandwidth in every engine.
