The INKOMA HSE high-performance worm gear screw jacks are designed for dynamic applications requiring medium to high lifting speeds and increased duty cycles. These jacks are ideal for heavy-duty tasks, with load capacities ranging from 500 kg (1,100 lb) to 100,000 kg (110 tons).
The housing is made of spheroidal graphite iron with integrated cooling fins, which enhances heat dissipation, ensuring reliable performance under high-speed and heavy-load conditions.
Features:
● Lifting capacities: 5 kN to 1000 kN
● Drive-motor speed: Up to 3000 rpm
● Screw Type: Self-locking trapezoidal machine screw (optional ball screw available)
● Lubrication:
Machine screw with grease lubrication
Worm gears with oil-bath lubrication
● Separate lubrication circuits for different components
● Gear Ratios: Two options – normal “N” and slow “L”
● Worm Gears and Shafts: Case-hardened and ground for durability
These HSE worm gear screw jacks are ideal for industries requiring high performance and reliability in mechanical engineering, automotive, power supplies, food processing, logistics, and more.
