Rubber Bellows
Rubber bellows are used to sealing environments, carrying liquids, slurry and gases, mechanical coupling, and performing electrical contact amongst other things. These bellows are durable and flexible. These bellows are type of cylindrical vessels which are readily compressible and extensible due to various annular convolutions. Rubber bellows are available in a wide variety of shapes, sizes, constructions and elastomer coated fabrics or rubbers to fit any specific applications needs.
Applications
- Aerospace
- Automotive
- Chemical
- Motion coupling
- Fluid coupling
- Electrical contacts
- HVAC
- High purity
- Marine
- Petrochemical
- Semiconductor
Features of Rubber Bellows
- Cryogenic rated bellow: They are used in cryogenic systems to handle very low temperature gases.
- Flange: This is a fitting, used to attach the bellows to equipment or piping.
- Hermetic sealing: Hermetic sealing on these bellows is used in high and low pressure applications. It is used in liquid or gaseous media.
- Medically rated: It is used to insure a high degree of sanitation.
- Necks: These are tube-like lengths running from the end of the bellows and
- Vacuum rated: This includes any vacuum application to very high vacuum.
Uses of Rubber Bellows
- These Bellows are normally used as covers on parts which needs protection from dust.
- These Bellows are of flexible types and have a good cushioning properties.
- They are of different shapes and types depending upon the fitment application.
Types of rubber used in Bellows
These are rubber molded products manufactured from different types of polymers:
- Ethylene Propylene Diene Monomer (EPM, EPDM)
- Hypalon
- Nitrile Rubber (NBR)
