Segbert ZPA-70-200-M Deflection shaft

The deflection shaft, also known as guide shaft, lead shaft, or web guide shaft, with OEM part number ZPA-70-200-M from Segbert, is a mechanical shaft for the precise guiding, redirecting, and controlling of the path of material webs, especially paper webs or substrates. It has the dimensions 10.5 x 6 x 44 cm and a weight of 8.84 kg. Deflection shafts ensure smooth material transport through the machine, preventing wrinkling, tension loss, and shifting of the web. Typical applications are found in printing presses, laminating machines, and packaging plants, where they ensure the exact positioning and stable throughput of web material.

In printing presses, a deflection shaft (Umlenkwelle) is a precision-engineered rotating rod or roller used to guide, redirect, and manage the travel path of the paper web or substrate. It ensures that the material moves smoothly through the machine without wrinkling, losing tension, or shifting off-center.
