    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.

    Image of Product. Front orientation. Bellows. 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.
