25 1/2" nylon precision bearing balls

Nylon 101 is one of the most widely used plastics in the world and the most popular non-metal bearing ball material. Nylon balls offer extremely good wear resistance, high tensile strength and modulus of elasticity. They also have high impact resistance, a high heat distortion temperature, and resist wear, abrasion, and vibration. In addition, Nylon 101 can withstand sustained contact with a wide variety of chemicals, alkalis, dilute acids or oxidizing agents. Compliant with FDA, USDA, NST, and 3A-Dairy regulations. Melting Temp: 500°F 260°C. Max Operating Temp: 210°F 99°C. Approximately 1/7 the weight of steel: Specific Gravity 1.14
