The SL2 safety coupling is compact, flexible and torsionally rigid with integral torque overload release. For aggressive servo driven applications, it is backlash free, relying on preloads and frictional connections, along with a hydroformed stainless steel bellows to relieve bearing loads resulting from misalignment. In the event of a machine crash, power surge, or any other cause of unanticipated overload, the SL2 will disengage the motor or gearbox shaft from the load in less than 3 msec. Re-engagement takes place automatically with slow speed rotation of the shaft subsequent to the overload occurrence. It is available in four sizes, and handles a range of disengagement torque values from 5 to 400 Nm, and English or metric shaft diameters from 12 to 60 mm.
