Spring couplings have been a part of powertrains for over 80 years. Torsion Control Products has developed a line of spring couplings, torque limiters, and torque converter clutches specifically for Tier III and Tier IV engine configurations. These products address the torsional characteristics unique to the Tier upgrades that produce more power in smaller packages at lower operating speeds. Through the evaluation of many different applications using Torsional Vibration Analysis, our engineers have created products that address the needs of most applications. Whether it is in Agricultural products, Mining, Industrial equipment, Marine or Construction applications, chances are we have a product/performance that will address the needs of your application. If we don’t have a current product that meets your needs, we will create a unique spring coupling, torque limiter, or torque converter clutch that meets the specific configuration and performance requirements of your application!
