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.
Mounting kits include hook-and-loop fasteners, mounting clips, mounting flanges, screws, and tape with adhesive on both sides to support different mounting options.

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.

Bridgeport Machine Bellows
Guard 9" and 12" travel Bridgeport milling machines by covering their rear knee/upper column and front knee. Do not use with Series II Bridgeport machines. 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. Mount these bellows to surfaces with screws.
