Tapered Round 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 moving parts, such as rods and shafts.
0.04″-0.07″ thick bellows are more durable than 0.02″-0.04″ thick bellows, making them good for applications where parts are constantly moving.

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.

Hydraulic Cylinder Bellows

Slip these bellows over hydraulic cylinder rods to keep them free from debris for a long service life. 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 are sized to fit standard hydraulic cylinders. Secure the cuff ends with the included hose clamps.
