Guide Rail Bellows

Also known as linear way covers, these bellows install on guide rails to protect the rails as carriages move across them. They have sealed seams to keep contaminants out. Air venting may be necessary in fast-cycling applications.

Bellows Mount Kits—Bellows mount kits include hook-and-loop fasteners, mounting clips, mounting flanges, screws, and tape with adhesive on both sides to support different mounting options.
