C7 (ISO 3408)

SFU Series Rolled Ball Screw Assembly

SFU1605 rolled ball screw assembly with C7 precision grade, 5 mm lead, and pre-loaded single nut — suited for 3D printers, laser engravers, and light CNC gantry axes where cost-efficient linear motion at ±0.05 mm/300 mm positioning tolerance is sufficient.

Grade: C7 (ISO 3408)
Size: 16 mm
