High Performance Gear Safety Warning When using Lovejoy products, you must follow these instructions and take the following precautions. Failure to do so may cause the power transmission product to break and parts to be thrown with sufficient force to cause severe injury or death. Refer to this Lovejoy Catalog for proper selection, sizing, horsepower, torque range, and speed range of power transmission products, including elastomeric elements for couplings. Follow the installation instructions included with the product, and in the individual product catalogs for proper installation of power transmission...

High Performance Gear

High Performance Gear The High Performance group of gear couplings consists of coupling designs that require additional engineering. While standard components do exist, the unique requirements of individual applications will customize a coupling design. Lovejoy High Speed and Engineered Special Gear Couplings JW 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. The Lovejoy /...

High Performance Gear Lovejoy / Sier-Bath F Type High Speed Couplings FHS High Speed Close Coupled This coupling is made from AISI 1045 steel. The design is similar to the standard “F” except the components are machined to tighter tolerances and controlled fits to allow higher operating speeds. The maximum speed is for assembly balanced couplings. Component balancing is available and may result in lower maximum speeds. FHSA High Speed Standard The Lovejoy / Sier-Bath High Speed Standard gear couplings are made of alloy steel with a core hardness of RC30-35, and they are magnetic particle inspected....
