7 CARDAN SHAFTS - COUPLINGS Alongside with the production of special gearboxes, our company has developed the production of Universal shafts, with the same high quality and accuracy. The production range covers the medium-heavy duty sector, up to a torque of Nm. Our technology also allows us to manufacture special universal shafts, for those application not included in the normal commercial products. Starting from the design and until the painting, each production step is controlled and verified in order to guarantee an excellent, top quality product. All the universal shafts produced must meet a series of strict controls, starting from the quality of the raw material up to the dynamic balancing (also for the big shafts), where the application requires it. Our company offers its customers the know-how and the experience in the field of the industrial design, to optimise and integrate its products, so as to increase the efficiency of the plants. We offer our technical support during the design, the installation, the maintenance and the evaluation of the performance. The main characteristics of a universal joint are: -its capacity of compensating high angles, thus allowing the transmission of the torque between two shafts not in line -In its version with double extensible joint, a universal joint will allow both radial and axial displacements. -It can transmit very high torques -it requires a very reduced maintenance -it is easy to install
