SIJIE provides compact, low-noise, and customized linear transmission solutions tailored for diverse industrial applications,
30-Ton Heavy-Duty Ball Screw Linear Actuators
This custom 30-ton heavy-duty ball screw linear actuator is engineered for high-capacity, precision linear transmission under demanding industrial environments.
Featuring an integrated mechanical limit design, this compact actuator offers exceptional structural rigidity while making motor installation remarkably easy and flexible. Unlike conventional lead screw jacks that demand secondary support, our advanced design requires no additional external guiding structures on-site, significantly simplifying your system layout, reducing assembly time, and optimizing spatial efficiency.
Self-Aligning Nut Screw Jacks
In typical welding and fabricated construction environments, angular misalignment is a frequent challenge during installation. For conventional screw jacks, even a minor angle error leads to severe, rapid wear on the trapezoidal lead screw and nut assembly.
To solve this industry pain point, our patented self-aligning nut screw jack automatically compensates for installation mounting angle errors up to +/-3°. By neutralizing these structural angular discrepancies, this innovative solution significantly reduces frictional stress, prevents premature thread degradation, and drastically extends the overall service life of both the lead screw and the nut.
Advanced Surface Protection & Wear Resistant Screw Jacks
To deliver exceptional longevity in hostile environments, our screw jacks feature a premium multi-layer anti-corrosion coating system (primer + topcoat). The linear lead screw undergoes a precision black chrome plating process, while the input shaft is treated with an advanced QPQ liquid nitriding (salt bath composite) treatment. This engineering-grade combination drastically minimizes frictional wear and maximizes heavy-duty corrosion resistance.
Custom-made food-grade stainless steel gearbox
Engineered for strict hygiene environments, SIJIE’s stainless steel gearboxes deliver ultimate corrosion resistance against heavy chemicals and high-pressure washdowns.
Built with highly standardized shaft layouts combined with H1 food-grade lubrication, these fully sealed units offer customized input flanges to seamlessly adapt to your precision servo motors and planetary gearboxes, securing both food safety and high-accuracy linear transmission.
