• lubricated with polymer greases at constant temperature. The tested greases were formulated with the same base oil (PAO) but different thickener content (polypropylene). The friction torque in rolling bearings produced by these greases was measured and the coefficients of friction under boundary and full film lubrication were numerically calculated through the approximation of the SKF friction torque model to the experimental results.
