Sealing bellows, method for the production thereof and sealing bellows arrangement

A method of producing a sealing bellows, the method comprising:

• producing, using vulcanization, the sealing bellows including a sealing region, an attachment region, and a substantially cylindrical casing that is disposed, in an axial direction of the bellows, between the sealing region and the attachment region, the sealing region being formed with an integrated first clamping element, and the attachment region being formed with an integrated second clamping element;
• interrupting the vulcanization after a mold cavity for the sealing bellows has been filled and after dimensional stability of the sealing bellows has been attained, and releasing the sealing bellows from the mold cavity;
• introducing the sealing bellows with the substantially cylindrical casing into a heated blowing mold having a substantially spherical cavity, the blowing mold being sealed in an airtight manner;
• subjecting an interior of the sealing bellows with the substantially cylindrical casing to a relative excess pressure such that the casing is applied against a wall delimiting the cavity of the blowing mold and thereby forms a substantially spherical casing;
• completing the vulcanization of the sealing bellows;
• and then
• opening the blowing mold and releasing the sealing bellows having the substantially spherical casing from the blowing mold.
