About Nylon GS|Nylon with graphite and silicon additive for improved wear resistance and reduced friction. Self-lubricating. Used for bearings, bushings, and sliding components where maintenance-free operation is required. Machines similarly to standard Nylon. Compare to Nylatron GS (same material, brand name) and standard Nylon (higher friction, less wear-resistant).
