The roller bearing coordinate measuring machines of the RA series offer a maximum measuring volume for medium-sized and large work pieces. The almost unlimited accessibility of the measuring area from all sides allows an easy placement and the shortest set-up times. An especially high measuring efficiency can be achieved by simultaneously using several measuring units. An expansion of the measuring volume is possible by combining various measuring units. The measuring machines of the RA series are supplied with new guide beams made from the modern material, polymer concrete. The outstanding physical qualities of polymer concrete offer the best conditions for high-precision measurements. The advantages at a glance: * Easy accessibility to measuring area * Long service life * Low maintenance * Multi-sensor capable
