RUBBER BELLOWS

 
 
300 different measures of rubber bellows

Rubber bellows are the core business of BARBIERI RUBBER, specialized in their design and production from more than 40 years.  

The use of a rubber bellows is varied, being simply a protection. It is normally installed on bodies with axial movement (pneumatic cylinders, hydraulic cylinders and linear actuators in general), but in other applications it protects organs with different movements (eg angular) or even stationary (shift cables, air passage). It can not be applied if there’s a difference in pressure between outside and inside.

 
  • 300 different measures of rubber bellows
  • Possibility to realize a new customized model
  • Choice between different materials
  • Modular bellows always in stock
  • Accessories 
The set of modular bellows is ideal for emergencies (being always in stock all sizes in two materials: NBR black and orange food grade silicone), for particular sizes because of the possibility to punch collars and to include joints to obtain different lengths and races permits to adapt the protection bellows on device.

 

 

 

modular rubber bellows adaptable to any size, race and lenght

 

For emergencies and samples you can find modular bellows on stock, adaptable to any size, race and length. For production with convincing quantities, it’s reasonable to realize new equipment from a studied purposely drawing or use one of the 300 models of bellows that we already have.
 
 
 
standard rubber bellows seriesThe series of standard bellows is made from articles in one piece injection moulded, typically with NBR ozone protected, so The series of standard bellows is made from articles in one piece injection moulded, typically with NBR ozone protected, highly resistant to oil and grease (even when immersed), but also moderately resistant to weather conditions. Some bellows are produced with EPDM, however, extremely resistant to weather conditions, but not to prolonged contact with oils and grease. If necessary it’s possible to produce the same bellows in many different materials: Silicone, Neoprene, Dutral, Viton ®, FKM, CR, VMQ, HNBR and others.  modular bellows
 
The modular bellows is made up of elements that can be fitted, designed and patented by BARBIERI RUBBER. It is the definitive solution to the exhausting search for a protection rubber bellows that is aesthetically pleasant and immediate available and with a much lower price than traditional bellows, sewn, glued or welded.  
 
They can be produced in many different materials: Silicone, Neoprene, Dutral, Viton ®, FKM, CR, VMQ, HNBR and others.modular bellows can be produced in many different materials   When rubber bellows have to replace a sewn or welded bellows it’s necessary to pay attention to the closed length. 
Because of the change in volume inside the protection bellows during closing and opening phases is often needed a breathing hole, in case of dusty or abrasive materials in suspension you can request a special filter that keeps clean all the air inside the body of the bellows.  
the rubber bellows should not be used in case of different pressure between outside and inside     The rubber bellows, modular or standard, should not be used in case of different pressure between outside and inside. If inside there is a depression it’s possible to fit steel rings inside the bellows coils to contrast the push of the pressure. Also resistant to the weight of a person and can be used as protection for the passage of cables or pipes to the ground
