SK 02040.1 Helical Worm Gear Units

NEW: We have thoroughly redesigned our two-stage SK 02040 Helical Worm Gear Units. The new SK 02040.1, made from high strength aluminium, replaces the previous product. The die-cast aluminium housing guarantees maximum strength and rigidity with low weight and can be further protected by additional measures such as the highly effective nsd tupH surface treatment. The SK 02040.1 has a wide power range from 0.12 to 1.1 kW and an output torque of up to 100 Nm. The wide range of speed ratios (from 5.37:1 up to 330:1) enables optimum adaptation to the customer's requirements. The motor can be mounted directly without a coupling or via an adapter (IEC or NEMA).

Suitcases on Tour at Hamburg Airport

There are several kilometres of conveyor belts at Hamburg Airport. In the baggage processing area they are used for combination, feeding, holding and sorting. An efficient organisation of transport and storage is essential. The reliability of the conveyor system and the prevention of faults ensured by powerful drive technology have top priority. NORD has implemented this and also fulfils the demands of the customer on its service providers with regard to service and maintenance.
