Worm Speed Reducer-Replacement of Nord Helical Worm Gear Unit SK43125
Product Introduction
The Worm Speed Reducer-Replacement of Nord Helical Worm Gear Unit SK43125 is a multi-stage helical gear device, with the motor shaft and output shaft forming a 90?? angle. This allows for flexible installation in situations with limited installation space. These gearboxes are made of high-strength aluminum or die-cast aluminum, ensuring maximum strength and rigidity while remaining lightweight. They can be further protected through surface treatments. This series has a wide power range, from 0.16 horsepower to 20 horsepower, with an output torque of up to 27,350 pounds per inch. The broad speed ratio range (from 5.37:1 to 330:1) can optimally meet customers' requirements, and the motor can be directly installed without a coupling or adapter (NEMA or IEC). Our company provides replacement Nord-brand helical worm gear reducers, which are of good quality and offered at a competitive price. It is important to note that our products are replacement parts and not original equipment manufacturer parts. If you need to purchase original equipment manufacturer parts, please contact the original supplier directly.

Structure of Helical Worm Reducer
The helical worm reducer consists of the following parts:
- Input shaft
- Worm gear
- Worm shaft
- Bearing
- Oil seal
The input shaft is connected to the motor shaft, and the worm gear is connected to the worm shaft. The bearing supports the worm shaft, while the oil seal prevents oil leakage. The worm gear is made of high-alloy steel with a surface-hardened tooth profile. The optimized geometry and precise shaft alignment provide excellent load capacity, long service life, and quiet operation. The worm stage has a hardened cylindrical worm and a worm wheel with special bronze rim welding, ensuring high reliability.
