The first step is to determine the maximum torque required. The clutch should be selected accordingly, whereby permanent use in the overload or absolute limit range should be avoided.

Misalignment plays a decisive role in terms of the service life of the clutch. Precise alignment is therefore essential, as a larger misalignment reduces the life expectancy of the coupling. The compensable lateral misalignment usually varies between 0.15 and 0.3 mm and is highly dependent on the number of bellows shafts. For example, a 4-shaft coupling has significantly higher possible misalignment values than a 2-shaft coupling. In general, the lateral offset is the decisive factor after the torque, as it has a considerable effect on the power transmission. A high offset can lead to unsteady operation, which in turn can manifest itself in increased wear, more noise or even damage to the entire drivetrain.

The measurement of the maximum operating temperature should also take into account the possible heat development of the machine and its components during operation. The choice of coupling material is also important in this context. For example, the lightweight aluminum often used is replaced by stainless steel components at very high temperatures.

The choice of hub type, the possible dimensions of the coupling or whether a safety element should be installed are also important questions.


Once all criteria have been taken into account, a suitable coupling can be selected. JAKOB Antriebstechnik also offers a configurator that guides the customer through these questions and offers possible couplings. If there are any uncertainties, the manufacturer will be happy to provide advice.
