TECAST T natural

PA 6 C

Ensinger TECAST T natural cast nylon offers a combination of good mechanical properties, excellent bearing and wear characteristics, and the large size capabilities of the casting process. The cast polyamide's fatigue resistance, noise damping ability, corrosion resistance, and light weight make TECAST ideal for metal replacement applications, such as bearings, gears, sheaves, and sprockets. At one-eighth the weight of bronze, TECAST is easier to handle and maintain than metals such as iron, aluminum, brass, and bronze, which it typically replaces in industrial wear applications.
