The nut-traveling screw jack is a game-changing solution for applications requiring precise linear actuation with minimal space occupation. Its core design revolves around a stationary trapezoidal or ball screw shaft, paired with a precision-machined traveling nut that meshes seamlessly with the screw thread. When the worm gear (driven by a motor or manual handle) rotates, it drives the nut to move along the fixed screw shaft, enabling accurate lifting, lowering, pushing, or pulling of loads without shaft rotation. This unique design eliminates the need for additional anti-rotation devices, simplifies installation, and ensures consistent performance even under heavy loads or continuous operation.

Ideal for both single-unit operation and multi-unit synchronization, our nut-traveling screw jack is widely used in automation, material handling, packaging, and industrial positioning systems. It supports both manual and electric drive modes, with customizable specifications to match your specific speed, load, and stroke requirements-making it a versatile choice for diverse industrial needs.

Unique Nut-Traveling Design: Fixed screw shaft and traveling nut structure eliminates shaft rotation, eliminating the need for extra anti-rotation components. This design ensures stable linear motion, reduces friction, and improves positioning accuracy, making it superior to traditional screw jacks in precision-critical applications.

High Precision Positioning: The precision-ground trapezoidal (or optional ball) screw thread and matched traveling nut ensure minimal backlash (≤5 arcmin for standard models, ≤3 arcmin for precision models), delivering positioning accuracy of ±0.1mm. This makes it ideal for applications requiring exact load placement, such as automation assembly lines and precision testing equipment.

Exceptional Load-Bearing Capacity: Constructed with high-strength alloy steel screw shafts (C45 or 20CrMnTiH) and aluminum bronze (ZQAl9-4) traveling nuts, our nut-traveling screw jack can handle rated loads from 2.5kN to 500kN. The heat-treated screw shaft (hardness HRC58-62) and wear-resistant nut ensure reliable performance under heavy loads and frequent use.

Self-Locking Performance: The trapezoidal thread design provides inherent self-locking capability, which can hold the load securely at any position without external braking devices. This feature eliminates the risk of accidental load dropping, ensuring operational safety in high-altitude or heavy-load scenarios.

Compact & Flexible Installation: With a cubic or compact housing design (multiple mounting faces available), the nut-traveling screw jack can be installed in horizontal, vertical, or inclined orientations, adapting to space-constrained environments. The fixed screw shaft design also simplifies integration with existing equipment, reducing installation time and cost.

Dual Drive Options: Supports both manual operation (ergonomic foldable handle) and electric drive (AC/DC motor, servo motor, or stepper motor) via flange adaptors. This flexibility allows it to adapt to both low-frequency intermittent operation and high-frequency continuous operation, meeting diverse application needs.

Our nut-traveling screw jack is designed to excel in a wide range of industrial applications, particularly those requiring precision, stability, and space efficiency. Key application areas include:

Automation & Robotics: Precision positioning of robotic arms, assembly line actuators, and automated guided vehicles (AGVs), where accurate linear motion and minimal backlash are critical.

Material Handling: Lifting and positioning of heavy loads, conveyors, lifting platforms, and palletizers. The fixed screw design ensures stable load movement without shaft rotation.

Packaging & Printing Machinery: Actuation of folding, sealing, and cutting mechanisms, as well as height adjustment of printing rollers-delivering consistent precision for high-speed production lines.

Medical Equipment: Precise positioning of medical beds, diagnostic equipment, and surgical tables, where reliability and accuracy are vital for patient safety.

Wind Power & Renewable Energy: Adjustment of wind turbine blades and solar panel positioning, with low-temperature models available to withstand harsh outdoor environments.

Steel & Metal Processing: Positioning of rolling mill components, detection platforms, and material feeding systems, handling heavy loads with high stability.

Agricultural & Construction Machinery: Actuation of farm equipment attachments and construction tool positioning, adapting to rugged working conditions with minimal maintenance.
