SFU1204 Ball Screw with Nut 12mm Diameter 1000mm Length High Precision Linear Motion Ballscrew with Machine Ending

SFU1204 Ball Screw with Nut 12mm Diameter 1000mm Length High Precision Linear Motion Ballscrew with Machine Ending SFU1204 Ball Screw with Nut is a high precision linear motion ballscrew with a 12mm diameter and 1000mm length.

• SFU1204 ball screw with nut designed for smooth, accurate positioning. This 12mm ball screw rod features a 4mm lead/pitch, providing controlled travel per rotation and supporting precise motion in CNC axes, DIY machines, and automation builds.
• Manufactured from durable GCr15 steel with C7 accuracy grade and a rolled thread process, this ballscrew is built for consistent performance and long service life.
• The included ball screw nut helps reduce friction compared to standard lead screws, improving efficiency, reducing drive power requirements, and minimizing heat generation.
• Its anti-backlash characteristics support more repeatable positioning—especially useful for vertical motion and precision alignment.
• For convenient installation, the screw includes machine ending / end machining, allowing secure attachment to common bearing blocks, couplers, and mounting systems.
