Rectangular Bellows
Slide these bellows over square rods and shafts. All are molded, which means they're airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. Screw mount the flange ends to surfaces, or add a mounting flange (sold separately) for stability.

Tapered Rectangular Bellows with Cuff End and Flange End
Attach the cuff end with a hose clamp (not included), and screw mount the flange end. Also known as boots, these bellows are often used on CV joints. All are molded, which means they're airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. Slide these bellows over square rods and shafts.

Three-Sided Flat Bellows
Slide these bellows over flat moving surfaces on machinery, such as guideways. They have a notched opening with four perforated tabs on each side that can be removed to widen the opening. The edges of the folds are reinforced with PVC. These bellows have sealed seams to keep contaminants out. Air venting may be necessary in fast-cycling applications. Add a mounting flange (sold separately) for stability.

Flat Bellows
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. All of these bellows meet UL 94 HB for flame retardance.

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.
