Lovejoy offers a large variety of motion control couplings to meet the needs of different applications, including beam, oldham, mini-jaw, bellows, mini-soft, mini-disc, and curved jaw couplings. Before you can determine which motion control coupling design is right for your application needs, you need to identify your requirements in different categories such as material, torque, torsional stiffness, bore capacity, maximum RPM, misalignment capacity, maximum temperature and moment of inertia. The Lovejoy Motion Control catalog includes a Quick Reference Chart which enables you to compare the performance characteristics of the different designs side by side.

Once the most appropriate coupling design has been identified, the next step is determining the proper size needed 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.

Lovejoy Motion Control Coupling Selection Criteria

You should have the following information available when selecting a motion control coupling:

  • Lovejoy Motion Control CouplingsHP 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)
