Typical “Stribeck” curves obtained by Martens showing coefficient of friction as a function of pressure in kgf/cm² (even if it looks like kg/mm²) at v = 0.5 m/s using water quenched, hardened steel shaft 99.6 mm diameter and 70.2 mm long, running in bearing shell made from “Rotguß” (red brass, a Cu-Sn-Zn cast alloy) with “Rüböl” (rape oil). The parameter lines represent temperature in °C.
