NORD's two-stage SK 02040 helical worm gear units have been redesigned as the new SK 02040.1 worm gear units. Made from high strength aluminum or die-cast aluminum, these units guarantee maximum strength and rigidity with low weight. They can be further protected with optional surface treatment. The SK 02040.1 has a wide power range from 0.16 to 20 HP and an output torque of up to 27,350 lb-in. The wide range of speed ratios (from 5.37:1 up to 330:1) enables ideal adaptation to customer requirements and the motors can be mounted directly without a coupling or adapter (NEMA or IEC).
