Plum Shaped  Aluminum Alloy Coupling for CNC Machine

* Clamp-style mount for secure attachment to shaft

* Accommodates angular, axial and parallel misalignment

* Aluminum hubs for light weight, stainless steel discs for strength

* Shaft couplers suitable for connect servo motor, stepper motor, encoder, screw driving, machine platform, etc.

* Flexible couplings are used to link 2 rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from 1 shaft to the other.

* Most flexible couplings consist of 2 hubs and 1 middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the 2 shafts.

* Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from 1 shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from 1 type of misalignment to another.

* Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

The shaft coupler is not elastic, can not modify the concentricity. Shaft must be located in a straight line. If your equipment is eccentric already, then it will make noise and cause off-centering.
