Standard Ball Screw Jacks: High-Speed & High-Efficiency Lifting Solutions
1. Product Overview
Ball Screw Jacks are the premier choice for applications requiring high operational speeds and continuous duty cycles. By utilizing a rolling friction mechanism with high-precision ball bearings, these jacks achieve superior transmission efficiency and low heat generation. This optimizes energy consumption and significantly extends the service life of the driving motor system.

2. Key Features
-
Superior Efficiency: The integration of a ball screw minimizes friction, achieving efficiency ratings of up to 0.64—2 to 3 times higher than conventional trapezoidal screw jacks.
-
High-Speed Operation: Perfectly suited for fast-paced automated production lines and rapid positioning tasks.
-
Extensive Load Range: Available in a full spectrum of models from 10 kN up to 1,000 kN, covering applications from light-duty to ultra-heavy-duty industrial lifting.
-
Anti-Rotation Option: Can be integrated with an anti-rotation mechanism to ensure the screw only performs precise linear translation without rotating.
-
Safety Note (Non-Self-Locking): Due to low rolling friction, these products do not have a self-locking function. A braking system (brake) must be equipped on the motor to hold the load safely.
-
Diverse Customization: Supports optional accessories such as bellows (dust covers), limit switches, and RC encoders.
