SIK Torque limiter couplings

The SIK torque limiter coupling is a coupling that provides protection against mechanical overload. In the event of a collision, the straightforward design directly reduces the torque in a few fractions of a second. No tools or intervention are required in order for power transmission to be restored; all it takes is a 360° rotation in the reverse direction. As a result, this coupling remains unbeaten with regard to continuous operation and is completely maintenance -free. It is assembled using the VMA quick clamping unit. The frictional connection results in a high level of torque and enables fast assembly.

Product versions

For direct drives, the torque limiter couplings are equipped with an attachment in the form of the tried-and-tested ASK sliced coupling or with metal bellows. Shaft offsets can be equalized in the same way. Under cramped conditions, the torque limiter coupling can also be fitted directly in the hubs, e.g., as in the case of a toothed belt pulley (or similar). The torque limiter couplings are available in 6 different versions.
