With a thrust of 17,000 N, IP67 protection, and temperature resistance down to -40°C, how does the HB-DJ805H heavy-duty pushrod pass the rigorous tests of industrial environments?

With a thrust of 17,000 N, IP67 protection, and temperature resistance down to -40°C—how does the HB-DJ805H heavy-duty actuator pass the rigorous tests of industrial environments?

In high-demand applications such as industrial automation, medical devices, and new-energy equipment, linear actuators are not merely “executing units”—they are the very cornerstone of system reliability. When the load exceeds 10 tons, the ambient temperature drops as low as -40℃, or continuous operation under IP67 protection is required, ordinary push rods often simply fall short of meeting these demands.

The HB-DJ805H series of industrial-grade electric actuators launched by Wuxi Hongba Mechatronics is setting a new benchmark in the field of heavy-duty linear drives, thanks to its maximum dynamic load of 17,000 N, IP66/67-rated protection across the entire product line, a dual-screw architecture featuring ball screws and trapezoidal screws, and modular signal and control interfaces.

I. Performance Breakthrough: Full-Link Optimization Supports 17,000 N Thrust

The HB-DJ805H doesn't achieve load optimization merely by simply increasing the motor size; rather, it involves comprehensive optimization across the entire chain—from the transmission system to the structural materials.

The twin-screw architecture can optimally balance efficiency and self-locking as needed.

Two types of transmission—ball screws and trapezoidal screws—are available in five different pitch options:

If an A-class ball screw is used, the efficiency can reach up to 90%, supporting a load of 17,000 N and a no-load speed of 6.5 mm/s, making it suitable for high-frequency, high-precision applications.

When equipped with a J-type trapezoidal screw, the 805H boasts inherent self-locking capability and can still withstand a static load of 15,000 N even after power failure, making it ideal for safety-critical applications such as lifting platforms and hospital beds.

Wide temperature range & high protection—handle extreme conditions with ease.

The 805H comes standard with an operating temperature range of -40℃ to +65℃ and features an IP67 protection rating (dustproof and short-term immersion resistance), enabling it to operate reliably in harsh environments such as outdoor photovoltaic mounting systems, cold-chain logistics equipment, and mining machinery.

Flexible duty cycle configuration balances performance and lifespan.

From 20% (high-load intermittent operation) to 35% (medium-load continuous operation), users can select the transmission gear according to their actual usage frequency, striking an optimal balance between performance and service life.

Example: Under operating conditions of a travel distance of 500 mm and a load of 12,000 N, selecting Gear A (ball screw) not only meets the requirements but also provides a higher safety margin and longer service life.

1. Smart Integration: Sensing and Communication Empower “Push-Pull” Approaches

Modern industrial equipment requires drives to possess both “sensing” and “communication” capabilities. The HB-DJ805H offers 8 signal feedback options and supports integration into intelligent control systems:

Basic limit protection: Built-in upper and lower limit switches automatically cut off the power to prevent overshoot;

High-precision position feedback:

Hall sensor: Achieves displacement monitoring at the ±0.1mm level through pulse counting and supports direction recognition;

Analog signal: 0–20mA or 0–5V signal, supporting connection to PLC or HMI;

External magnetic switch: Supports on-site, non-destructive adjustment of stroke length without the need to return to the factory, significantly enhancing debugging flexibility. Meanwhile, five control modes cover all scenarios—from traditional relays to industrial buses:

① Simply reverse the positive and negative terminals of the power supply to extend and retract the piston rod.

② Logic level control;

③ Hand controller adaptation;

④ Synchronous control;

⑤CANbus bus: Supports centralized scheduling of complex systems and reduces wiring costs.

3. Highly Customized: From installation spacing to connectors, perfectly tailored to every inch of space.

Industrial equipment features compact spaces and diverse interfaces. The HB-DJ805H addresses the “last centimeter” adaptation challenge with its highly modular design:

Travel range 50–1000mm, supporting a 14,500N load under ultra-long strokes (>600mm);

Installation distance from intelligent computing:

The basic formula is L ≥ stroke + 200 mm, and it is dynamically adjusted based on the transmission code (A/B requires an additional 30 mm), the stroke range (601–1000 mm requires an additional 100 mm), and the type of connector (e.g., F13/F14 requires an additional 40 mm) to ensure structural safety.

14 types of front-end connectors + 7 types of rear-end connectors: available in various forms such as through-holes, external threads, internal threads, and spherical bearings; the hole orientation supports 0°/90° rotation, making it suitable for any installation position.

Piston rod diameters of Ø30/Ø35 are available; for high-load applications, the diameter can be upgraded to Ø35a to enhance rigidity.

IV. Application Scenarios: From the Operating Table to Photovoltaic Power Plants, Empowering Thousands of Industries and Sectors

The high-load and high-reliability features of the HB-DJ805H make it the preferred choice for several high-value applications:

Smart Healthcare: Electric hospital beds, surgical table lifts, and rehabilitation training equipment—quiet operation (≤65 dB), self-locking safety, and EMC compatibility;

Industrial Automation: Press assist, fixture opening and closing, material lifting platform (high frequency, high load, vibration-resistant);

New energy equipment: Photovoltaic tracking bracket pitch drive (wide temperature range, IP67 rating, UV-resistant and aging-resistant);

Special vehicles: RV lift steps, engineering vehicle outriggers (standard equipped with emergency manual operation; also functional during power outages).

Whether or not the specific operating conditions of the equipment are thoroughly considered during selection will directly affect product performance. Therefore, Hongba provides end-to-end support—from requirements analysis and 3D modeling to prototype testing—to ensure that you make the right choice the first time.
