Lovejoy High Speed and Engineered Special Gear Couplings satisfy a specific engineering need for custom coupling designs that require additional engineering. While standard components do exist, the unique requirements of individual applications will customize a coupling design. (For stock gear couplings, please see our Gear Couplings
High Speed - The Lovejoy / Sier-Bath F Series High Speed gear couplings are designed for exacting high speed, high efficiency performance beyond the ranges and limits of standard coupling specifications. Typical applications include high speed centrifugal and axial flow compressors, gas turbines, steam turbines, test stands, etc. High speed couplings are dynamically balanced as assemblies and match marked. Fasteners are weigh balanced in sets. Major diameter fit gear teeth, precision machined tolerances, and high quality components help to reduce the potential unbalance in the coupling assembly.
Engineered - Many of the components are standardized, but the special requirements of certain applications will customize each design. These couplings require specific customer input to properly design the coupling to suit the application.
