Polyurethane couplings are used to prevent the axial leakages of shafts, absorb the vibration, bind the shafts, in the places where axis parallels and leakages can not be got rid of completely and every kind of power transport safely. They prevent vibration of writhe and reduce effects of stroke. Polyurethane couplings are balanced as static and dynamics; they can be worked at both two sides and used vertically and horizontally. Their installations are easy and subjected to heavy dynamic loads. They have tear resistance and -40 °C +80 °C is ideal temperature for them. There are many kind of couplings produced by Panel such as; flexible couplings, circular couplings, daisy couplings, Lombardini star couplings, beet motor couplings, polyurethane eder couplings, Alarko star couplings, H-type couplings, Lister couplings, Clutch couplings, Water motor couplings, etc. Moreover, cement couplings and wedge of couplings can be produced with various shapes.
