HIWIN FSI Series R8-2.5T3-FSI High-precision Ball Screw

Model Meaning:

“R”: Indicates a right-hand-rotating ball screw.
“8”: Represents a nominal diameter of 8mm.
“2.5”: Refers to a 2.5mm lead, meaning the nut moves 2.5mm along the screw axis for each screw rotation.
“T3”: 3×1
“FSI”: “F”: Flange-mounted nut, “S”: Single nut, and “I”: Internal recirculation.

HIWIN R8-2.5T3-FSI ball screw adopts internal circulation structure, smaller nut outer diameter, and more compact overall structure, which is very suitable for automation equipment with limited installation space. Compared with traditional ball screws, FSI effectively reduces the occupied space while ensuring transmission rigidity and precision, making equipment design more flexible. Its small but efficient characteristics are especially suitable for use in volume-sensitive occasions such as micro positioning platforms, desktop CNC systems, and testing equipment.
