If you’re looking for a high-performance, cost-effective solution for converting rotary motion into precise linear movement, the 3205 SFU series ball screw is a standout choice. Widely used in industrial machinery, automation systems, and CNC equipment, this component delivers the accuracy, durability, and smooth operation your applications demand. In this guide, we’ll break down its key features, specifications, and why it’s a go-to option for engineers and manufacturers worldwide. What Is a 3205 SFU Series Ball Screw? At its core, a ball screw is a mechanical system that translates rotational motion into linear motion using recirculating ball bearings. The 3205 SFU model refers to a specific configuration: • Shaft Diameter: 32mm • Lead: 5mm (the distance the nut travels with one full rotation of the screw) • SFU Series: A standard metric design known for its compatibility, ease of integration, and reliable performance in general industrial applications. This design is engineered to minimize friction, maximize efficiency, and ensure consistent positioning accuracy over millions of cycles. Key Specifications of the 3205 SFU Ball Screw The 3205 SFU ball screw from Shuntai is built to meet the most common industrial requirements, with flexible customization to match your project needs: Feature Details Core Material GCr15 bearing steel, renowned for high hardness, wear resistance, and long service life. Manufacturing Process Rolled screw shaft (cold rolling technology), balancing precision and cost-effectiveness. Precision Grades Available in C3, C5, and C7 grades to suit different accuracy needs (from general automation to high-precision CNC). Size Range Standard diameter: 5mm to 65mm; Lead options: 3mm to 300mm; Length: 10mm to 6000mm (custom lengths available).
