SFU3205 3.175mm Grinding Self-lubricating Heavy Duty Ball Screw
The ZLV SFU3205 3.175mm Grinding Self-lubricating Heavy Duty Ball Screw is a high-performance component designed to meet various industrial needs. It stands out for its excellent precision, high efficiency, and superior speed.
Characteristics
- Low Friction Loss, High Transmission Efficiency: As there are many balls rolling between the screw shaft and the nut, the SFU3205 ball screw provides high efficiency. Compared to traditional sliding screws, it requires less than one-third of the driving torque, thus saving energy.
- High Precision: This product is made using the highest level of mechanical equipment globally. It controls temperature and humidity strictly during production, ensuring maximum precision.
- High-Speed Feed and Micro Feed: The SFU3205 ball screw has a minimal starting torque due to its rolling motion, preventing crawling phenomena and enabling precise micro-feed.
- High Axial Stiffness: By applying preload, axial clearance can be negative, resulting in higher rigidity.
- No Self-locking, Reversible Transmission: It delivers reliable and reversible transmission, which is beneficial for various industrial applications.
Composition and Classification
The SFU3205 ball screw consists of a screw, nut, steel ball, preload piece, reverser, and dust protector.
Classification:
- Self-lubricating Ball Screw: This product comes with a detachable oil removal device, eliminating the need for lubrication systems and equipment and reducing oil change and waste oil handling costs.
- Silent Ball Screw: With a special groove-shaped ball spacer between balls, it suppresses collision noise, offering smooth and quiet operation.
- High-speed Ball Screw: Suitable for fast-feed tool machines, high-speed cutting centers, and high-speed vertical load cutting centers.
- Heavy Load Ball Screw: Suitable for all-electric design machines, air compressors, semiconductor manufacturing devices, and forging and pressing devices.

| Nut Unit-price/pcs (USD) | 9 |
Specific Parameters
- Nominal Diameter: It refers to the external diameter of the screw.
- Lead: Lead signifies the linear distance that the nut moves when the screw rotates one full rotation. The relationship between the lead (i) and the moving speed (v) of the nut, and the rotating speed (r) of the screw is:v = r * iThe relationship between the lead (i) and the thrust (F) of the screw, the torque (T) provided by the motor, and the transmission efficiency (n) is:F = (2 * π * T * n) / i
- Length: It involves two concepts – overall length and thread length. The thread length comprises two parts – total thread length and effective stroke.
- Nut Form: Various types of nut forms exist, depending on the flange type and nut length. There are differences between single and double nuts in terms of preload adjustment, price, and length.
- Accuracy: The accuracy levels for ball screws vary across different countries and regions. SFU3205 conforms to high precision levels, making it suitable for applications demanding high precision.
Conclusion
The ZLV SFU3205 3.175mm Grinding Self-lubricating Heavy Duty Ball Screw is a versatile, high-performance component that offers unparalleled precision, efficiency, and speed. Its advanced characteristics make it suitable for a wide range of industrial applications. The product is customizable and offers several advantages, including low friction, high axial stiffness, and reversible transmission, making it a preferred choice for various applications.
