The Lovejoy D-8 universal joint coupling is a slow friction bearing universal joint, only capable of 1750 RPM.
At Twin Spring we have a no greasing/bearing replacement. The Twin Spring design absorbs vibration and one ball bearing allows the coupling to flex to 45 degrees.
Offering high speed (Up to 7000 rpm) and high torque (up to 500ft lbs. nominal static torque)
The Twin Spring Coupling is a great maintenance free replacement for the Lovejoy D-8
