Showing the single result

The  L-110 jaw coupling is available in 4 different configurations, SOX, Ureathane, Hytrel and Bronze.

At Twin Spring we don’t offer any because we don’t use spider inserts. 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 L-110 jaw coupling
