The Must be Enough Clearance Around The Air Bellow
- The full surface of the metal parts is to be used to bear the forces.
- Air bellows must be equipped with lateral guides.
- Deflate the air bellows fully before removing.
- Ensure that the bellows is not constantly in contact with hydraulic oil, lubricants, solvents, metal cuttings and weldin sparks.
- Should the air bellow be subjected to special media in an application, ask Precision Engineering for further information, specifying the medium, temperature and concentration.
