Coupling Hub for 7/16" Shafts

The Lovejoy L075 jaw coupling hub fits a 7/16 inch round bore and uses a set-screw locking method. It is made from carbon steel with a straight jaw profile and an outside diameter of 1 3/4 inches. This hub is intended for mechanical power transmission assemblies that use the L075 coupling size.

Speed and Power Limits by Spider Type

Maximum rotational speed is 11,000 RPM. At 100 RPM the hub transmits 0.14 hp with a Buna-N spider, 0.21 hp with a urethane spider and 0.36 hp with a Hytrel spider. These figures define the practical torque ceiling for each compatible centre element. Exceeding the rated speed or horsepower for the chosen spider can cause premature wear or failure.

Bore Diameter Decides Fit

The single specification that determines whether this hub is the correct part is the 7/16 inch bore diameter. The hub accepts only shafts of that exact size with a set-screw flat. Buyers who need a different bore diameter, a keyway connection or a metric shaft cannot use this hub.
