Bellow
Bellows are protective seals, consisting of flexible bellows and two end segments for attachment. Depending on application, bellows and end segments can have very different geometrical configurations and dimensions.
Application:
Bellows protect axially moving rods and machine parts from dirt, spray, dust, or climatic influences. Depending on their design they can accommodate transverse movements or a combination of motions, parallel with and perpendicular to the axis.
Operating Conditions:
Bellows are able to follow axial movements within their limiting values (compressed length and extended length).
