Hollow Threaded Rod

Short hollow lead screw (or short hollow threaded rod) is a compact mechanical component characterized by its brief length, external threading, and hollow inner bore. It retains the core advantages of standard hollow lead screws-such as reduced weight and the ability to route cables or small rods through its center-while being optimized for space-constrained applications.

Typically made from materials like carbon steel, alloy steel, or stainless steel (based on strength, corrosion resistance, or precision needs), it excels in scenarios requiring limited linear adjustment or compact motion transmission. Common uses include small-scale machinery, precision fixtures, lightweight support structures, or auxiliary components in automation, where its short length ensures efficient space utilization without sacrificing the functional benefits of a hollow design.

2-meter hollow lead screw is a long, threaded mechanical part with a hollow center. Made usually from steel, it's designed for scenarios needing extended length-like large-scale construction supports (for height adjustment) or long-stroke machinery (for linear motion transmission). Its 2-meter length meets demands for wide-range movement, while the hollow core reduces weight and allows space for cables or small rods to pass through, balancing functionality and practicality.

ultra-long hollow lead screw (or extra-long hollow threaded rod) is an extended-length mechanical component characterized by its exceptionally long structure, external threading, and a hollow inner bore. It integrates the functional advantages of both ultra-long and hollow designs, making it ideal for scenarios requiring large-scale linear transmission, extended adjustment ranges, or weight optimization in long-distance applications.

Common applications include large-scale construction formwork systems (for wide-range height adjustment), heavy machinery with extended motion paths (such as bridge cranes or industrial elevators), and long-distance automation lines (where it converts rotational motion into linear movement over extended distances). Its design addresses the challenges of balancing strength, weight, and space efficiency in ultra-long mechanical transmission or support tasks.
