Product Description

Ball screws are ideal components for converting rotary motion into linear motion, or linear motion into rotary motion. They consist of a lead screw, a nut, steel balls, preload washers, a reversing device and a dust cover. Ball screws are transmission elements used in machine tools and precision machinery, and their primary function is to convert rotary motion into linear motion.

Features and Advantages

● Extremely high transmission efficiency

Rolling friction with a coefficient of friction as low as 0.002–0.005 results in low starting torque and low energy consumption, making it suitable for high-speed applications and scenarios involving frequent starts and stops.

● Extremely high positioning and repeatability accuracy

Precision grinding and cold rolling processes ensure minimal pitch error, with positioning accuracy down to the micrometre level and repeatability of ≤±1 μm. The absence of sliding friction wear ensures excellent long-term dimensional stability.

● High rigidity and load capacity

The angular contact structure with a large contact angle allows paired bearings to withstand both radial and axial loads simultaneously. Multi-point ball contact ensures uniform load distribution, making it suitable for heavy-duty applications and precision positioning.

● Reversible transmission

Capable of converting rotary motion to linear motion, or linear motion to rotary motion; non-self-locking (requires a brake); suitable for servo closed-loop systems.

Product Applications

Applications requiring high levels of precision, efficiency and rigidity, such as CNC machine tools, precision grinding machines, industrial robots, semiconductor equipment, medical instruments, automated production lines and measuring equipment.
