The reason why the rubber air spring can replace the traditional
pneumatic or hydraulic cylinder is because it has the following
outstanding advantages
Low design height: Compared with the traditional cylinder, the air
bag air spring has no piston rod, which can greatly reduce the
design height and make the structure more compact.
Low cost of ownership: Compared to conventional cylinders, air bag
air springs are not only low-cost to purchase, but also cost less
due to their long service life and no maintenance.
Economical and easy installation: When not inflated, the air bag
air spring is quick and easy to install, saving time and money.
Moreover, the product has good elasticity and can compensate for
small deviations.
Allowable lateral eccentricity: The lateral eccentricity of the
airbag air spring can be up to 30mm, within which the reliability
of the work can still be maintained. Unlike air or hydraulic
cylinders, bladder cylinders have no seals that can jam or wear,
and do not require precision guides that are susceptible to dust
and other impurities.
Frictionless means Maintenance free: Airbag air springs work
effectively even in poor operating conditions. Since there are no
parts (seals) that rub against each other in the bladder-type
cylinder, there is no wear even when working in an environment with
a lot of dust, particles or sediment.
