SFU 3210 Ball Screw Nut | 32mm High-Precision Linear Motion Nut
The TriQuench SFU 3210 Ball Screw Nut is a heavy-duty linear motion component designed for high-performance CNC transmission systems. Featuring a substantial 32mm diameter and a 10mm lead (pitch), this nut is engineered to deliver high-speed travel while maintaining exceptional axial rigidity. The SFU series utilizes an external circulation system with a single flange design, providing a robust architecture that excels in demanding industrial environments such as large-format CNC routers and milling machines. Manufactured from high-tensile alloy steel with induction-hardened raceways, the 3210 nut ensures minimal friction, high repeatable accuracy, and superior wear resistance. Its design is optimized for zero-backlash performance when paired with precision-ground or rolled SFU3210 ball screws, making it an essential component for machine builds requiring high-load stability and surgical precision.

Technical FAQ & Operational Guide
What is the benefit of a 10mm lead (pitch) over a 5mm lead?
A 10mm lead allows for faster linear travel per revolution of the ball screw, making it ideal for large CNC routers where high-speed positioning is required on the X and Y axes.
Is this nut compatible with all 3210 ball screws?
While it follows standard SFU 3210 dimensions, we highly recommend pairing it with TriQuench SFU series ball screws to ensure the ball track matching and pitch accuracy required for smooth operation.
How often should I lubricate the 3210 ball nut?
For industrial CNC use, we recommend a high-quality lithium-based grease. Re-lubrication should occur every 100km of travel or every 3-6 months depending on the workshop environment and debris levels.
