This article deals with the design and assembly of a component for determining the frictional properties of elastomeric vulcanizates. The component was design for a universal tensile machine, without needed of intervention to itself machine. The purpose of the work was designing a component in software SolidWorks and its subsequent assembly, as well as individual testing of frictional properties of selected specimens of elastomeric vulcanizates. Before of individual testing, the elastomer blends have to be vulcanised in the form of a block with a constant 16 mm height to ensure the same spring pressure on the specimens in the component. Then, by using rotary knife is from prepared vulcanizate cut a sample with 16 mm diameter. Result from friction properties measurement of samples is force needed to start of movement (shear) of sample over particular type of surface as well as graphical dependence of force (N) on movement of track (mm). From the graphical dependence, it is possible to determine the decrease or increase the force depending on the individual sections of the trajectory.
