Flexible air shock absorber rubber bellow

The shock absorber rubber bellow surrounds a moving area with a flexible dust cover. Its folded profile accommodates a defined stroke while helping keep loose dirt away from the protected surfaces. The product information describes light environmental protection in industrial and automotive assemblies; the cover itself does not provide the damping action of a shock absorber.

Start the fit assessment with the mechanism at both ends of its travel. The cover needs room to close its folds without becoming a solid obstruction, and enough available length to extend without pulling its attachment ends loose. Also consider the position reached when equipment is lifted or serviced, which may differ from its normal working position.

Custom dimensions, material, hardness and color are available. These choices should follow the movement envelope and the surfaces used to retain each end. After fitting, move the assembly slowly and look for a fold touching a neighboring edge. Remove packed dirt gently during maintenance so the folds can continue moving, and replace a cover with a split wall before contamination reaches the exposed mechanism.
