The INKOMA HSGK High Performance Screw Jacks are designed for demanding applications, offering exceptional durability and performance. Equipped with oil lubrication and cooling fins, these jacks ensure optimal operation even under extreme conditions. With robust construction and carefully selected materials, they provide high efficiency and a long lifespan.
Product Highlights:
- Sizes: Available in models from HSGK-3 to HSGK-9
- Load Capacity: Supports both compressive and tensile loads up to 1000 kN
- Input Speed: Up to 3000 rpm
- Cooling Fins: Enhanced heat dissipation for extreme conditions
- Materials: High-quality grey cast iron housing, precisely machined fixing faces, recessed oil level indicator, and ventilation screw
- Spindle Types: Available with trapezoidal or ballscrew spindles
- Gears: Worm wheel driven by hardened and ground gears with optimized geometry
- Support: Needle rollers support radial loads on the spindle for increased life and performance
- Design Options:
- Rotating version (R): Provides linear lifting through spindle rotation, with the spindle axially fixed.
- Translating version (S): The spindle moves axially to lift the load, with travel limitation and rotation prevention available in versions like SA.
Features:
- Wide range of accessories available for customization
- Input speeds up to 3000 r/min and high load-bearing capabilities
- Designed for both compressive and tensile loads
For specific questions, custom designs, or special requirements (e.g., rust-resistant versions or modified housing), consultation with the INKOMA team is recommended to tailor the system to your needs.
