Roulage Mazaud

The instrument is compose by:
– Support plate of sample perpendicular to the load support axis that
rotates in a orizontal plane to a 93 ± 2 RPM speed throught a
electrical engine
– Vertical axis perpendicular to the support plate where it’s fixed
the wheel. The wheel supported a group load applied according to
the standard patent pending N°202018000004419
– A wheel holder group that allows the wheel to rotate and oscillate freely with integrated air copressed cooling system PATENT N°0000283275
