Worm Speed Reducer-Replacement of Nord Helical Worm Gear Unit SK42125
The Worm Speed Reducer-Replacement of Nord Helical Worm Gear Unit SK42125 is a multi-stage helical worm gear unit where the motor shaft and output shaft form a 90° angle. This allows for flexible installation in limited mounting spaces. These gearboxes are made of high-strength aluminum or die-cast aluminum, ensuring maximum strength and rigidity while being lightweight. They can be further protected through surface treatment. This series has a wide power range, from 0.16 horsepower to 20 horsepower, with output torque of up to 27,350 pound-inches. The broad range of speed ratios (from 5.37:1 to 330:1) ensures optimal fulfillment of customer requirements. The motors can be directly mounted without the need for couplings or adapters (NEMA or IEC). We offer Nord brand replacement of helical worm gear reducers, which are of high quality and offered at competitive prices. It is important to note that our products are replacement parts and not original equipment manufacturer (OEM) parts. If you require OEM parts, please contact the original supplier for purchase.
