Standard Screw Jacks: Industrial Lifting Solutions (10kN – 1000kN)

1. Product Overview

Our Standard Screw Jack series is the result of intensive research and development by a leading manufacturer in the power transmission industry. With specialized expertise, we provide a highly reliable lifting device featuring a robust structure that meets the most stringent standards in heavy industry and automation.

2. Key Technical Features

• Wide Load Range: Capacities ranging from 10 kN to 1000 kN, suitable for systems of all scales.

• Self-locking Mechanism: The perfect combination of high-precision worm gears and trapezoidal screws ensures the load is held safely at any position without the need for additional braking systems.

• Effective Anti-rotation: Screws are made from high-grade carbon steel. Optional keyways and anti-rotation pins provide precise control over linear motion.

• Durable Operation: The reduction mechanism is lubricated with standard grease to reduce friction, ensure low noise, and extend operational lifespan.

• Diverse Accessory Ecosystem: Flexible integration with bellows (dust covers), handwheels, trunnion bases, limit switches, and RC encoders for automated control.

3. Detailed Technical Specifications

Below are the basic parameters for models ranging from J0G to J7A:

4. Performance & Operating Conditions

• Drive Efficiency: Ranges from 0.09 to 0.22, depending on the gear ratio (H – High speed or L – Low speed).

• Temperature Resistance: Operates stably within a temperature range of -15°C to 80°C (for smaller models) and up to 100°C (for high-capacity models from J4A and above).

• Lubrication: Optimized grease volume ranges from 0.1kg to 11kg depending on the unit size.
