AIR BELLOWS

Product catalog summary

Company Overview: Manufacturas Oria, part of the Egaña Group, specializes in the design and manufacturing of industrial air bellows. Established in 1970, the company leverages over 50 years of experience and advanced technologies.

Product Description: Oria bellows are corrugated flexible bodies made from high-quality materials, including rubber covers, reinforcing fabric plies, and steel beads. They are available in single, double, and triple convoluted designs with central rings.

Design Alternatives: The air bellows can be configured with three design alternatives: Dismountable Design, Bead Ring Design, and Crimped Design, each offering different assembly and fixation methods.

Metallic Parts: Standard metallic parts are electro-galvanized steel, with options for stainless steel (AISI-304 and AISI-316L) for enhanced durability and resistance to harsh media.

Pressure Specifications: Standard air springs operate at a maximum pressure of 8 bar, with a four-ply construction option available for pressures up to 12 bar.

Working Media: Designed primarily for compressed air, the bellows can also handle nitrogen, oil, water, and oil-containing compressed air. Stainless steel parts are recommended for water applications to prevent corrosion.

Storage Recommendations: Rubber bellows should be stored in cool, dark, and dry conditions, away from direct sunlight and ozone-producing equipment, following ISO 2230 guidelines.

Elastomer Compounds: Various elastomer compounds are available, each with specific temperature ranges and resistance properties, including Natural (NR/SBR), Chlorobutyl (CIIR), Nitrile (NBR), Ethylene Propylene Diene (EPDM), and Chloroprene (CR).

Advantages as Isolator: Air bellows offer uniform isolation properties, extended machinery life, height control, effective noise reduction, and compact installation height. They can isolate loads up to 380 kN per bellow.

Advantages as Actuator: Air actuators provide lateral misalignment absorption, compact installation height, extended product life, wide size range, tilt motion capability, low purchasing cost, and uniform movements.

Technical Specifications: Detailed specifications for D Series and F Series models are provided, including dimensions, stroke, force at 7 bar, design height, and natural frequency.

GENERAL INFORMATION Manufacturas Oria is a global company (member of Egaña Group) specialized in industrial air bellow product design and manufacturing. Established in 1970, we rely on more than 50 years of manufacturing knowledge and experience, counting with advanced technologies and qualified personnel. The Oria bellow is a corrugated flexible body composed of high-quality materials. An inner and outer rubber cover with reinforcing fabric plies in between and steel beads are joined vulcanized together, producing single, double and triple convoluted bodies with central rings among convolutions....

PRESSURE The maximum allowable pressure during operation when using a standard construction air spring is 8 bar pressure. In case of being required a greater pressure, it should be consulted to the manufacturer or distributor. Oria air bellows can be supplied with an alternative four-ply construction (high strength construction). The advantage of the four-ply version air actuator is that it is able to work with higher pressures, achieving greater forces. Basically, the four-ply air bellow has a pressure capability of 12 bar. METALLIC PARTS The metallic parts of the air bellows can be supplied...

ADVANTAGES AS ISOLATOR Due to air springs extremely low natural frequency, they can be used instead of coil springs or other types of isolators, obtaining the following advantages. Best Isolation Degree in the Market The rubber bellow isolator is able to absorb more than 99% of the unwanted vibrations. Uniform Isolation Properties The air isolators maintain constant natural frequency values with changing loads. Extended Product Life Air springs are unaffected by weathering and can be manufactured with a wide range of elastomers and steel qualities, being suitable for use in harsh ambient conditions....

ADVANTAGES AS ACTUATOR The air actuator has been developed to be used instead of traditional rigid actuators such as pneumatic or hydraulic cylinders, adding the following benefits: Maintenance Free Due to the rubber bellow long-life service (without sliding sealing elements), the operational costs are lower than a conventional cylinder. The purchasing cost of a rubber actuator is much lower than a conventional pneumatic cylinder. Lateral Misalignament Absortion Due to their flexibility, the air bellows can operate with lateral misalignments up to 30 mm, reducing costs by avoiding use of precision...
