24" Cast Nylon Low Friction Stub Shaft The benefit of using a cast nylon stub shaft is the extremely low amount of friction that they produce to meet your needs for your clarifiers. They also offer a longer working life and low maintenance. These Cast Nylon stub shafts actually decrease the amount of overall energy used due to the extremely low friction. Most steel shafting and wall bearing clarifiers use more energy to articulate the collector chains due to the high friction they produce under the weight of the sludge, and the weight of material. Steel components are much more prone to corrosion then Cast Nylon. Overall, Cast Nylon sprockets and shafting eliminate corrosion, has a much higher wear life, extends the life of the chain and sprockets, and uses less energy.
