R300
R300 roundness tester is one of the best devices worldwide for the characterization of surfaces, born from thirty years of experience boasted by SM in this field, it was specifically designed to measure bulky and heavy pieces, with utmost accuracy.
R300 features 3, pneumostatically supported, metrological measurement and positioning axes that ensure fluent movements without frictions and remarkable sturdiness of the entire system.
The main application of R300 consists in the characterization of large size bearings, where all those essential characteristics for the final quality of the product must be determined, among which roundness and race angles, which are measured by following the piece's profile with more axes working at the same time, thus generating a considerable number of measurements.
