Lovejoy Coupler, L070 X 9/16"

Lovejoy Coupler, L070 X 9/16"

The Lovejoy L070 Jaw Coupler Hub (9/16" Bore) is a durable flexible coupling hub designed for use in L070 jaw-type coupling systems commonly found in motors, pumps, and power transmission equipment. Manufactured from sintered iron, this hub works with an SOX NBR rubber spider insert to transmit torque while absorbing vibration and shock loads. The jaw-style coupling design eliminates metal-to-metal contact, allowing the elastomer insert to handle misalignment and protect connected equipment. With a 9/16" bore and 1/4" × 1/8" keyway, this hub provides a secure shaft connection for reliable mechanical power transfer—because smooth-running machinery starts with components that work together instead of grinding against each other.
