SFU 3210 Precision Ball Screw | 32mm Diameter | 3000mm Length
The SFU 3210 Precision Ball Screw is a high-performance linear drive component engineered for demanding industrial environments. With a robust 32mm shaft diameter and a high-lead 10mm pitch, this ball screw delivers an exceptional balance of high-load carrying capacity and rapid linear speed. The 3000mm length is precision-rolled from high-grade hardened steel, ensuring minimal deflection and surgical positioning accuracy over long travel distances. This unit features professional end-processing specifically machined to accommodate standard BK25/BF25 or BK20/BF20 support blocks, allowing for seamless integration into heavy-duty CNC router axes, industrial milling centers, and automated gantry systems. The SFU internal circulation design ensures low-friction movement, reduced thermal expansion, and long-term durability under high-duty cycles.
- Large 32mm diameter for superior rigidity and high load capacity
- High-lead 10mm pitch for increased linear travel speed
- Precision-ground end processing for BK25/BF25 and BK20/BF20 supports
- 3000mm continuous length for large-format machine axes
- Hardened bearing steel construction for maximum wear resistance
- Low-friction motion with zero-backlash potential

Technical FAQ & Operational Guide
Is the SFU 3210 nut included with the screw?
Yes, our SFU 3210 3000mm assembly typically includes the high-precision ball nut. The nut features internal circulation and integrated dust seals to protect the ball tracks.
What is the benefit of the 32mm diameter over a 25mm screw?
The larger 32mm diameter significantly increases axial rigidity and prevents 'whipping' or vibration over the 3000mm span. This is essential for maintaining precision in heavy-duty machines where high cutting forces are present.
Does this come with the BK25/BF25 support blocks?
While the screw is pre-machined for these supports, the blocks themselves are usually sold separately to allow you to choose the bearing grade that best fits your application. We stock both standard and high-precision support block sets.
