Metal Telescoping Bellows

Made of coiled spring steel, these bellows protect equipment from hot and sharp chips. Slide them over moving parts, such as rods and shafts, and their spring action will hold them in place as they extend and retract between two parallel surfaces. Choose a bellows with an ID that's at least _1/4" larger than the diameter of the item to be covered.

Wear-Resistant Breathable Round Bellows with Flange Ends

Made of Kevlar, these are the most durable breathable round bellows with flange ends. They also protect against sparks and weld spatter. Slide these bellows over moving parts, such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.

High-Temperature Breathable Round Bellows with Flange Ends

These fiberglass bellows withstand temperatures up to 450° F—about twice as much as standard breathable round bellows with flange ends. They also protect against flames and sparks. Slide these bellows over moving parts such as rods and shafts. Sewn seams let them breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.

High-Temperature Flat Bellows

These bellows withstand temperatures up to 500° F—more than twice as much as standard flat bellows. Use them to guard flat moving surfaces on machinery. Sewn seams let these bellows breathe, so they retract quickly in fast-cycling applications. The seams will allow small amounts of moisture and dust to pass through.
