R20-5T4-FSI HIWIN High-rigidity Screw FSI Ball Screw

Model Meaning:

“R”: Indicates a right-hand-rotating ball screw.
“20”: Represents a nominal diameter of 20mm.
“5”: Refers to a 2.5mm lead, meaning the nut moves 5mm along the screw axis for each screw rotation.
“T4”: 4×1
“FSI”: “F”: Flange-mounted nut, “S”: Single nut, and “I”: Internal recirculation.

HIWIN R20-5T4-FSI ball screws have unique advantages in high-frequency and light-load automation systems, such as dispensing equipment and electronic component packaging equipment. Its low friction characteristics and small inertia structure can achieve fast start and stop, effectively improve the response speed and reduce system delay. Due to the small size of the nut and the lower inertia load, it is more suitable for use with stepper motors or small servo systems. Especially in situations where continuous operation or frequent starting is required, FSI ball screws can maintain good operating stability and reduce mechanical shock and motor burden. At the same time, its silent characteristics can also reduce operating noise and improve the working environment. For smart production lines that focus on efficiency and stability, FSI is the preferred transmission element with both performance and cost-effectiveness.
