 The selection process for determining the proper Motion Control coupling starts with selecting the coupling design that best addresses the application requirements. The Lovejoy Motion Control Coupling Quick Reference Chart of the Motion Control catalog,
provides a method of weighing performance characteristics of the Beam, Bellows, Mini-Disc, Oldham, Mini-Soft, Curved Jaw, and Mini-Jaw couplings. |

|
 Each coupling is compared side by side in critical categories such as: material, torque, torsional stiffness, bore capacity, maximum RPM, misalignment capacity, maximum temperature and moment of inertia. Once a design is selected, the proper size
must be determined based on the capabilities of the particular design. |
|
|
 The Beam, Bellows and Mini Disc designs all have a single piece construction, so only one part needs to be selected. The GS curved jaw, Oldham, Mini Soft, and Mini Jaw designs have a three piece constructions, consisting of two hubs and an
insert. When the shaft size of the driver and driven are the same diameter, the hubs will be the same. When the shaft diameters differ, the hubs selected will differ accordingly. |

 The following information is necessary before a coupling can be selected:
- HP and RPM of the driver
- Shaft size of the driver and driven
- Application requirements
- Environmental conditions (i.e. extreme temperature, corrosive conditions, space limitations)
- Space Limitations (i.e. maximum outside diameter and overall length for the coupling)
