A Type Coupling Provides the possibility of mounting to a large diameter shaft with a small coupling diameter due to the narrow coupling diameter of the elastic parts. Since it is manufactured from three parts, it provides the opportunity to replace the elastic parts without removing the coupling from the shaft on which it is mounted. Otherwise, when the elastic parts deteriorate, metal works against metal and the feet break. Type B Coupling is the form of A type made of two parts. It is suitable in price, the hub to which the shaft is connected has a large diameter and it is very suitable for use where the distance between the shafts is very narrow, but it is necessary to completely disassemble one side to replace the elastic parts.
