Oldham couplings are used to connect parallel shafts that are slightly out of line, this kind of parallel misalignment can occur where power transmission is needed at different elevations. They are best suited for applications where precise positioning is required, such as in material handling or general automation and assembly. Bellow couplings can accommodate all forms of misalignment and have a balanced design for reduced vibration at high speeds. Gear couplings are flexible and capable of high torque transmission between shafts that are not collinear, because of this they are frequently use on large industrial machinery where high power applications are needed. The types of couplings that sit within the flexible couplings area are gear couplings, Oldham couplings and universal joint couplings.

They are easy to install and have a long-life span. These couplings can improve the performance of a machine and reduce wear and tear. Flexible couplings are used where a degree of motion is needed between the shafts. Rigid couplings are used where precise alignment is of paramount as there is no movement between the shafts with this coupler type.

When deciding which shaft coupler is best, many considerations need to be factored in to ensure the correct coupling is used to reduce instances of coupler failure, improve system capability, and reduce system issues.

Which Coupling Type should I choose? There are many different coupling types, shapes and sizes, the right choice of coupler will be dependent upon your applications and specifications. A coupling is a mechanical element that connects two shafts together to transmit power and movement. Flexible Couplings "Couplings, or couplers, are commonly used in a variety of motion control applications, from aviation and laboratory equipment to robotics, and medical devices.
