Siemens' ARPEX ARW is a low maintenance coupling able to handle a high offset of up to 3.0. It is applicable for papermaking machines, wind turbines, rail drive systems and replacing cardan shafts. It has a closed flange form and a large displacement capacity, as well as different intermediate spacer lengths, customized per each customer's needs. It can withstand temperature extremes from –40°C to +280°C. It is also suitable for potentially dangerous and explosive environments.

ARW couplings are already well known as an ideal alternative to cardan shafts. It is the solution to drive requests with higher demands on the coupling's displacement potential.
