A stop ring is a mechanical element that prevents the unwanted movement of a machine’s elements.
The ends of the stop rings can be open, overlapping, with one or more folds. These elements can be used as:
- Rings for interiors mounted on holes
- Outdoor rings mounted on pins
- Circlip
Generally speaking, Mollificio Modenese’s production (internal link at https://www.mollificiomodenese.it/azienda/) strongly focuses on special made-to-measure, non-standard and customer-designed parts, both in medium and large series as well as in samples or limited series. In the specific case of stop rings and seeger rings, our creations are exclusively special and do not include standard pieces.
