Create-Your-Own Round Bellows with Flange Ends
Built With Two Mounting Flanges, Two Bellows, One Link, And One Support
Interlock bellows, mounting flanges, and links to create a custom-length bellows. These molded bellows are airtight to keep contaminants out. Air venting may be necessary in fast-cycling applications. Mount these bellows to surfaces with the mounting flanges. Slide them over moving parts, such as rods and shafts.
Mounting flanges fit on the ends of each custom-length bellows. Drill a hole to fit your machine part.
Links connect multiple bellows.
Supports fit inside links to add stability. They are required when connecting three or more bellows. Drill a hole to fit your machine part.
Breather vent allows air venting. Drill a hole in the flange to mount the vent.
