How is nylon used in gears, bearings, and pulleys?

Nylon is a versatile synthetic plastic material that serves as an important engineering plastic due to its high resistance to wear, heat, and chemicals.1

In mechanical applications such as gears, bearings, and pulleys, nylon is utilized because it exhibits high stiffness, toughness, strength, and chemical inertness. These properties allow molded nylon parts to perform reliably in machinery where durability and shape retention are required. Furthermore, nylon's ability to be formed through injection molding—where it can flow effectively around complicated inserts—makes it an ideal material for manufacturing precise components like gear wheels and pulleys.21
