Meet Pen-type Actuator HB-DJ 875: Redefining Reliable Actuation in Space-Constrained Applications

Avoiding exposed motor housings and eliminating the need for complex mounting brackets, Hongba Mechatronics’ industrial-grade pen-type linear actuator HB-DJ875 integrates the motor, gearbox, and drive system coaxially into a highly compact unit—redefining reliable motion control where space is at a premium.

From HB DJ830 to DJ830P and DJ830G: A Customer Driven Evolution in Heavy Duty Linear Actuators

Against the backdrop of rapid advancements in industrial automation, intelligent equipment, and high-end manufacturing, linear actuators—as critical motion components—directly determine the operational efficiency and service life of end-use machinery through their performance, reliability, and customization flexibility. Since launching its classic model, the HB-DJ830, Hongba Mechatronics has earned widespread customer trust thanks to its robust mechanical design, stable electrical performance, and broad industrial compatibility.

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?

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.

Hongba Mechanical & Electrical’s 2025 Annual Light and Shadow Report: Are you satisfied with this performance report?

In 2025, Hongba Machinery & Electronics (HB) will, with a spirit of “crossing mountains and seas,” have its industrial actuator products installed in 284,448 devices across 52 countries worldwide, while covering 33 provincial-level administrative regions within China. Its products have already deeply empowered over 70 specialized sectors—from medical surgical beds and ocean-cleaning vessels to photovoltaic power plant heliostat arrays and agricultural harvesters—achieving precise motion control and reliable operation. In Rostov-on-Don, Russia, Hongba’s pushrods are employed in the track-tensioning system of F Company’s grain harvesters. Thanks to a triple-seal design and drainage structure, these pushrods can withstand muddy, dusty, and highly humid environments. In City R, South Korea, 806 pushrods are supporting S Group’s waste-collection vessels, ensuring stable operation even in highly saline and corrosive conditions. At a concentrating solar power plant at the northern foot of the Tianshan Mountains, more than 14,000 817T pushrods precisely drive heliostats under extreme climatic conditions, guaranteeing a 25-year service life. Throughout the year, Hongba’s ecosystem provides drive products for projects with an installed capacity exceeding 550 MW, expected to generate 880 million kilowatt-hours of electricity annually and reduce carbon dioxide emissions by 5.11 million tons. In 2025, Hongba delivered an impressive performance through technological innovation and global expansion. In 2026, Hongba will continue its mission of “cultivating new frontiers, crossing oceans, and chasing the sun,” driving global industrial upgrades and promoting green development.
