PowerGuard Bellows (Manufactured in Germany)

Robust Formed Bellows

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.
