High-Speed Screw Jack – Compact, Lightweight, and Powerful
Key Features
-
Capacity: 2kN / 5kN / 10kN
-
Equipped with a quadruple-thread (4-start screw) and high-lead design, enabling lifting speeds 2–5 times fasterthan standard screw jacks (H) at the same input rotation speed.
-
Compact and space-saving housing, with mounting holes designed for both top and bottom installation.
-
Wide range of options available, including dustproof bellows to protect the lifting screw, limit switches for stroke control, and RC encoders.
-
Note: This type of jack does not have a self-locking function; a brake must be installed for safe operation.
Advantages of Using Nippon Gear High-Speed Screw Jacks
-
Fast lifting speed – significantly faster than standard screw jacks.
-
Flexible design – easy installation in multiple orientations.
-
Ideal for industrial applications requiring high speed and efficiency, such as machinery, mechanical systems, and automation equipment.
