The GWZ 5116 is a backlash-free, torsionally stiff metal bellows coupling in line shaft design. Because of the double cardanic system, the compensating of high shaft displacements are possible. Due to the flange connection, the radial mounting is possible. Torsionally stiff and flexible line shafts are used in applications where torque and rotational motion combined with the highest possible angular precision should be transmitted or considerable distances between shafts need to be bridged. The application range of line shafts covers almost all technical areas, where mechanical power transmission and stiffness are important: Torsionally flexible line shafts with elastomeric spider Absolutely backlash-free Installation length up to 4 m possible Compensation of axial, radial and angular misalignment Cost-effective, simple assembly Maintenance free Variable length of the intermediate steel or aluminium tube Backlash-free elastomeric spider Excellent transmission of torque and...
