Shutai explains the following situation for you Ball screws are usually made of the following materials: 1. Shaft material: Commonly used shaft materials include carbon steel, alloy steel and stainless steel. These materials have high strength and good stiffness, making them suitable for applications with high loads and torsional forces. 2. Nuts: Common materials include brass and alloy steel. Brass nuts have good wear resistance and self-lubricating properties, while alloy steel nuts have higher strength and wear resistance. 3. Balls: Balls are usually made of steel and have high hardness and wear resistance. Ball diameter and material selection will depend on the requirements of the specific application. It should be noted that the material selection of the ball screw will also depend on the specific requirements of the application, such as load, speed, environmental conditions, etc. Therefore, specific application scenarios may require selecting a suitable material combination.
