The Worm Speed Reducer-Replacement of Nord SMI Worm Gear Units SK1SMI31 is a modular worm gear unit that covers five industry standard center distances ranging from 31mm to 75mm, with a torque capacity range of up to 3,779 pound-inches. The product offers a wide range of standard, single worm, and compound worm ratios, ranging from 5:1 to 10,000:1. The series' features include a smooth exterior surface and independent foot and flange gearboxes, ensuring excellent modularity. This flexibility allows for various input and output mounting options, as well as various output shaft options. SMI worm gear reducers have a high power density and a very compact structure. They are characterized by low noise torque transmission. Compared to other types of worm gear reducers, SMI worm gear reducers have a simple and effective design, giving them a considerable advantage in installation space. There are two types of SMI worm gear reducers: smooth surface type and enclosed surface type. Our company provides Nord brand replacement SMI worm gear reducers that are of good quality and competitive price, emphasizing that our products are replacement parts for original equipment manufacturers, and if you need to purchase original equipment, please contact the original equipment supplier.
