NUODUN NDL Series Bevel Gear Ball Screw Jacks are the result of extensive engineering development, with the NUODUN team dedicating tens of months to design, validation, and more than one year of field-application testing. The outcome is a new generation of high-performance lifting units that deliver higher speed, higher load capacity, and superior positioning accuracy—within a more compact structure.

The NDL Series integrates precision-ground spiral bevel gears with high-efficiency ball screws, achieving exceptionally low input torque, high duty cycles, and rapid linear motion. The hardened spiral tooth bevel gear transmission allows high rotational efficiency and stable operation at elevated lifting speeds.

Engineered for modularity, NDL Screw Jacks can be used as single units or configured into multi-spindle systems with mechanical or electrical synchronization. This makes them ideal for demanding applications requiring synchronized lifting, precise positioning, and long service life.

Types

Translating Type

The lifting shaft moves linearly through the gearbox while the integrated rotating nut drives motion. Ideal for applications requiring stable, controlled translation.

Rotating Type

The lift shaft rotates and moves the load via a traveling nut. Suitable for systems with long stroke requirements and high operational frequency.

Keyed Translating Type

A built-in anti-rotation mechanism prevents the screw shaft from turning, ensuring pure linear motion. Recommended for applications that cannot provide external anti-rotation guides.
