摘要

The bellow (10) has folds, coil regions (14, 15) and ring grooves provided with a base for receiving a clamping unit. A joint region is arranged between one of the folds and the grooves and serves as a joint for the fold. The joint region has a linear expansion in a direction of axis that proceeds via the coil regions and parallel to the base in an area of about 0.25 millimeter (mm) to 10 mm. The unit is provided with a mounting aid.
