High-Lead Ball Screw Jacks: High-Speed & Energy-Efficient Lifting Solutions
1. Product Overview
The High-Lead Ball Screw Jack is specifically engineered for applications demanding rapid duty cycles and superior lifting velocities. By optimizing the screw lead, this product line delivers significantly higher operational efficiency than conventional screw jacks, aligning with the latest trends in industrial automation.
2. Key Technical Features
-
Rapid Lifting Velocity: Featuring a high-lead design, this equipment achieves lifting speeds several times faster than standard ball screw jacks at the same input RPM.
-
Superior Energy Efficiency: Utilizing a rolling friction mechanism between the nut and the screw, the efficiency of this series is 3 times higher than that of Trapezoidal (Trapezoidal) Screw Jacks, minimizing power loss and reducing energy consumption.
-
Versatile Load Range: A broad product range supporting loads from 4 kN to 200 kN.
-
Anti-Rotation Mechanism (Optional): Can be integrated with an anti-rotation unit to prevent the lifting screw from rotating, ensuring precise linear translation.
-
Extensive Accessory Ecosystem: Supports the installation of bellows (dust covers), trunnion bases, limit switches, and RC Encoders for precise position control.
-
Safety Note (Non-Self-Locking): Due to the extremely low rolling friction, this product does not feature self-locking. A dedicated braking system is mandatory to hold the load safely.
3. Standard Technical Specifications (RSF – J4F Series)
Use the following table to select the model that best fits your requirements:
| Model Series/Size | Capacity (kN) | Screw Dia. (mm) | Lead/Pitch (mm) | Max. Input Speed (min⁻¹) |
| RSF | 4 | 16 | 16 | 2000 |
| J0F | 10 | 20 | 20 | 1800 |
| J1F | 25 | 25 | 25 | 1800 |
| J2F | 50 | 36 | 36 | 1800 |
| J3F | 100 | 40 | 40 | 1800 |
| J4F | 200 | 50 | 50 | 1800 |
Important Technical Note: For input speeds exceeding 1,000 min⁻¹, the device must be oil-lubricated to ensure proper heat dissipation and maximize service life.
