High-precision Ball Screw R25-5T3-FSI HIWIN Ball Screw for CNC Machine

Model Meaning:

“R”: Indicates a right-hand-rotating ball screw.
“25”: Represents a nominal diameter of 25mm.
“5”: Refers to a 2.5mm lead, meaning the nut moves 5mm along the screw axis for each screw rotation.
“T3”: 3×1
“FSI”: “F”: Flange-mounted nut, “S”: Single nut, and “I”: Internal recirculation.

During the use of HIWIN R25-5T3-FSI ball screw, daily maintenance is essential to maintain its high precision and long life. The following are the maintenance points for FSI series ball screws, which are suitable for reference by most industrial equipment maintenance personnel and purchasers:

1. Regular lubrication
The rolling contact parts of the ball screw need good lubrication to reduce friction and wear. It is recommended to add suitable grease or lubricating oil regularly, and adjust the lubrication cycle according to the operating speed, ambient temperature and load conditions. The lubrication frequency should be increased in dry or high dust environments.

2. Clean the surface of the screw
The surface of the screw should be kept clean to prevent dust, metal chips and other impurities from entering the nut, causing the ball to get stuck or the surface to be scratched. It can be wiped with a soft cloth without fiber and debris, and a special cleaning agent can be used.

3. Rust protection
If the FSI screw is installed in an environment with high humidity, it is necessary to regularly check for signs of rust, and apply anti-rust oil or use a lubricant with anti-rust ability.

4. Operation status inspection
Regularly observe whether the sound of the screw is stable, and whether there is abnormal vibration, jamming or noise. If any abnormality occurs, problems such as centering error, ball shedding or lubrication failure should be promptly checked.

5. Tightening and installation inspection
Check whether the installation parts such as the screw support seat and the locking nut are loose. Due to the internal circulation structure, the FSI screw rod relies more on a stable installation environment to ensure transmission efficiency.

Regular maintenance can not only extend the service life of the HIWIN FSI ball screw rod, but also maintain the stability and accuracy of the equipment operation. It is an important link that cannot be ignored in equipment management.
