SFNU3205-813-961-C7: Precision 32mm diameter rolled ball screws and nuts

The SFNU3205-813-961-C7 rolled ball screw belongs to Hojama's SFNU series, featuring a 32 mm diameter, 32 mm lead, 961 mm total length (including an 813 mm thread length), and C7 precision class, which means the repeat positioning accuracy is ±0.05 mm/300 mm. Designed with a compact steel ball nut, Hojama's SFNU series rolled ball screw kits excel in space-constrained applications, such as general machine tools, industrial machinery, and automated equipment.

Core Features of Hojama rolled ball screw assemblies

1. High Efficiency: Rolling friction between the rolled screw shaft and nut reduces the driving torque by over 2/3, requiring only 1/3 of the power compared to conventional lead screws. With a transmission efficiency of up to 96%, our rolled ball screw set ensures energy-saving operation.

2. Preload Capability & High Rigidity: Available with zero, light, medium, or heavy preload options. Preloading eliminates axial backlash (achieving negative clearance) for enhanced rigidity and extended service life.

3. Long Service Life: The nut and screw shaft of the rolled ball screw boast a hardness of HRC58-62, while the balls reach HRC62-66. Combined with rolling friction, the design delivers exceptional fatigue resistance and precision retention when properly specified.

4. High Precision: Stringent temperature and humidity control during grinding, assembly, and inspection processes, paired with a robust quality management system, ensures consistent precision.

With more than ten years of expertise in manufacturing high-precision ball screws, Hojama offers a comprehensive product range, including rolled ball screws, precision ball screws, bi-directional ball screws, and miniature ball screws. We also provide custom solutions tailored to specific requirements, covering dimensions, shaft end machining, surface treatments, and material selection. For inquiries or custom orders, feel free to contact Hojama anytime.
