Anti vibration rubber stopper snap-in bumper

A snap-in rubber bumper uses a retained feature to locate its cushioning face in a mounting opening. The stem or retaining section must engage fully before the exposed face can work in its intended position. Custom size, material and color allow the stopper to follow the mounting wall and contact arrangement.

Check the opening and the space behind it before insertion. The retaining feature needs room to pass through and settle without being cut by a burr or trapped against nearby hardware. Push using the intended supported area, then inspect that the face sits squarely rather than tilted above a partly inserted stem. Evaluate contact only after that fit is correct. During maintenance, look for movement at the mounting point when the opposing part reaches the bumper. A loose stem can make the whole part rock instead of allowing the rubber face to cushion naturally. Replace a torn retainer after checking the hole condition, so the same sharp or unsuitable edge does not damage the next part.

Material options

Custom rubber compound and color, selected for the contact conditions and required geometry.

Hardness range

30–90 Shore A for rubber. Assess the grade against this fit requirement: The stem or retaining section must engage fully before the exposed face can work in its intended position.

Check the opening and the space behind it before insertion.

Assembly considerations

Evaluate contact only after that fit is correct.

Design check
