Properties common to all products in this list

Grade: Nylon 66 Composition: PA 66 - (C₁₂H₂₂N₂)ₙ Form: Rod Material: Polyamide (PA) CAS Number: 32131-17-2 Commodity: Polymers
Nylon 66 Rod combines high stiffness, abrasion resistance, and dimensional stability with excellent load-bearing capacity, making it well-suited for precision-machined components. In solid rod form, it offers exceptional compressive strength and wear resistance, ideal for producing gears, bushings, rollers, and mechanical spacers. Industries including automotive, industrial machinery, and robotics rely on Nylon 66 rods for parts that must operate under mechanical stress, elevated temperatures, and exposure to oils or fuels. Specific uses include high-load bearing sleeves in conveyor systems, gear wheels in motion assemblies, and insulative mechanical couplers. In research, these rods are employed for fatigue testing, polymer machining evaluations, and tribological performance studies under varying lubrication conditions. The combination of Nylon 66’s mechanical resilience and rod geometry’s strength ensures dependable function in demanding industrial and scientific environments.
