R+W Offers Compact, Flexible Safety Coupling

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 three 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 five to 700 Nm, and English or metric shaft diameters from 12 to 60 mm.
