New! PEEK (Polyether Ether Ketone): A high-strength, heat-resistant engineering polymer. Lightweight, dimensionally stable, and excels in demanding, high-performance applications l ike bearing retainers.Si₃N₄ (Silicon Nitride): An ultra-hard ceramic that’s lightweight, wear-resistant, and exceptionally smooth, making it ideal for high-performance, low-friction bearing balls.New! Nylon 66 (PA66): A type of nylon, is known for its high strength, rigidity, and wear resistance, making it suitable for mechanical parts.Teflon (PTFE):Extremely low coefficient of friction, excellent chemical resistance, high-temperature stability, and non-stick properties. Glass: hard, smooth, and corrosion-proof material that offers low friction and good wear resistance, but is brittle under heavy impact.Stainless Steel: Strong, corrosion-resistant, and moderately heavy, with versatile finishing at a reasonable cost. Tungsten: Extremely dense and hard, delivering maximum weight and momentum in a compact size for a premium, planted feel. Please see our Sping Section to pair these High-end precision balls. 10 pieces per order of Teflon, Silicone Nitride, Stainless Steel, to Tungsten; standard sizes for function and on all fidgets with the correct sizes, these balls are the perfect make for anyone looking to DIY, experiment, or replace their old balls.
