Product detail
The SFS02505 Ball Screw is a miniature precision linear transmission component designed for compact motion systems that demand high accuracy and smooth operation.
Featuring a 5mm screw shaft and 5mm lead, this small-size SFS ball screw converts rotary motion into precise linear motion with excellent efficiency and repeatability.
Its recirculating steel ball structure ensures low friction, minimal backlash, and long operating life.
Manufactured from hardened bearing steel (GCr15 / SUJ2) and finished by precision grinding, the SFS02505 provides superior accuracy, quiet performance, and stable operation even under continuous micro-motion cycles.
