Making use of the existing EKL line of compact elastomer couplings, the all new SLE safety coupling offers a compact, flexible and vibration damping option with integral torque overload release.

Designed for aggressive servo driven applications, the SLE is completely backlash free, relying on preloads and frictional connections, along with a precision molded, wear resistant, polyurethane insert to damp vibration and relieve bearing loads resulting from misalignment.

In the event of a machine crash, power surge, or any other cause of unanticipated overload, the SLE will disengage the motor or gearbox shaft from the load in less than 3 milliseconds. Re-engagement takes place automatically with slow speed rotation of the shaft subsequent to the overload occurrence.

Available in four sizes, the SLE handles a range of disengagement torque values from 5 to 700Nm, and English or metric shaft diameters from 12 to 60mm.
