How does a Linear Chain work?

Designed for applications with space limitations, a Linear Chain can operate in both directions – it can pull and "push". Here, we take a look at the benefits that linear drive alternatives can bring to your application, using those offered by GROB Antriebstechnik as an example.

ROB Antriebstechnik’s Linear Chain is made of specially formed links, whose geometry prevents the chain from buckling under heavy loads. Unlike traditional linear drives, where significant installation space is needed for the spindle stroke, the Linear Chain can be rolled up efficiently into a small storage area. This is due both to the design of the drive housing and to the special profile of the chain links, with interlocking fingers.

How the chain "pushes"
Through the drive element, typically an electric motor, thrust force is applied to the chain links. The shoulders of the individual chain links then press against each other, forming a rigid unit. This allows them to lift or push the load. Thus, the chain becomes a rod that surpasses the cylinder in terms of range, load capacity, speed, and precision. Additionally, the Linear Chain can be practically "infinitely" long, while a lift cylinder cannot simply be extended.
