Product detail
The SFS2525 Ball Screw is a precision ground linear motion component engineered for demanding automation and CNC applications.
It features a 25 mm screw shaft and 25 mm lead, ideal for systems requiring high-speed, long-stroke, and stable linear transmission.
With its recirculating steel ball design, the SFS2525 achieves over 90% transmission efficiency, reducing friction and ensuring smooth, accurate positioning.
Manufactured from high-grade bearing steel (GCr15 / SUJ2) and treated through heat-hardening and precision grinding, it delivers outstanding rigidity, durability, and long service life — even under continuous heavy-load operation.
Key Features
25mm Shaft Diameter / 25mm Lead: High-speed transmission with fast linear displacement per rotation.
