In various sectors such as the pharmaceutical industry, shafts that are far apart have to be connected. Spacer couplings have been developed in order to avoid complex and cost-intensive design work for the necessary intermediate bearings. The EWLC spacer coupling from Enemac with an overall length of up to 3 m has a variable-length intermediate tube made of A2 or A4 stainless steel, which is adapted to the customer’s requirements. This tube is connected with two metal bellows couplings made of A4 stainless steel. In many cases, the spacer coupling can be used as a backlash-free connecting, cardan or synchronous shaft. Misalignments, especially parallel misalignments, can be compensated for to a considerable extent with this type.
The half shell hubs facilitate assembly and ensure a secure, non-positive connection. The spacer coupling is particularly torsionally stiff and is suitable for high operating speeds up to 6,000 min-1 with a low moment of inertia. It is available in seven sizes with a nominal torque of up to 1200 Nm.
