SK3 | Torque Limiter Coupling

With Conical Clamp Connections
For Direct Drives

The SK3 is a torque limiting coupling with and actuation ring that moves upon disengagement and can be used to trigger an external sensor. The actuation ring has a one to three millisecond response time which helps provide fast, reliable overload protection at preset (Adjustable) torque levels.
The frictional clamping connection provides for absolutely backlash free operation. The steel tapered conical clamps include jack screws for ease of adjustment and removal.
Made from high strength, hardened steel, the torque limiting portion delivers precise, reliable overload protection. The bellows are made of highly elastic stainless steel.
This coupling will deliver a long maintenance free service life while operated within the technical specifications.
It is a backlash free, low inertia, torsionally rigid solution. Once the torque limit it met, the SK3 disengages within one to three milliseconds with low residual friction after disengagement. This is generally much faster than electronic solutions that typically have reaction times between fifteen and seventeen milliseconds.
Faster response times translate to less wear and tear on equipment, which saves on downtime and expenses.
