PowerGuard Bellows (Manufactured in Germany)
Heavy-Duty Formed Bellows for High Temperatures & Challenging Environments
This style of bellows is designed for high temperatures and aggressive operating conditions. They exhibit excellent dimensional stability and can be further stabilized by means of wire rings or coil springs. A zip fastener can be added to facilitate retrofitting. Typical applications include industrial plants, automotive, printing, ball screw or piston rod cover.
Note: This type of bellows is manufactured at Dynatect’s production facility in Germany

Robust Formed bellows can be customized to include internal guides. Below is more information on the additional options.
An internal guide is a structural component installed inside a bellows to prevent the bellows from resting on the covered part. It consists of an inner hub, which interfaces with the moving component being protected (such as a screw, shaft, or spline), and a guide plate, which supports and guides the inside diameter of the bellows.
Internal guides are inserted inside the bellows and ride along the covered component to maintain alignment during extension and compression. As the bellows expands and compresses, the internal guide helps control motion, prevent snaking or twisting, and ensure consistent tracking over long travel lengths.
Internal guides are necessary when the bellows is protecting a moving mechanical component such as a ball screw, acme screw, spline, or rotating shaft. Guide selection depends on orientation, travel length, speed, and the component being protected.
Types of Guides
Note: Each guide requires a minimum overall clearance of 0.75” – 1” depending on the type used.
