R12-2T3-FSI HIWIN High-precision Screw HIWIN FSI Customization

Model Meaning:

“R”: Indicates a right-hand-rotating ball screw.
“12”: Represents a nominal diameter of 8mm.
“2”: 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 R12-2T3-FSI ball screws adopt an internal circulation channel design to effectively reduce the collision and noise during the movement of steel balls. Compared with the external circulation structure, the internal circulation is more stable and runs more smoothly, so the entire system remains quiet at high speeds, which is suitable for equipment with strict requirements on noise, such as medical testing systems, laboratory automatic control platforms, etc. In addition, smaller vibrations also mean lower wear rates, extending the service life of the screw and nut and reducing maintenance costs
