All of the parts that are shown with crimped bead plates
are also available with bead rings. (Bead plates are not
suitable for some applications.) Typical examples of
where bead rings are often used follow:
1. Where parts are stacked to increase stroke
(See page16).
2. Where the air spring is being used as a boot or
flexible connector (See page 29).
3. When used as an Airmount isolator with an auxiliary
reservoir (See page 24).
4. When air must move in or out of the unit at an extremely
fast rate (and a 3 / 4 " NPT air inlet is too small).
5. When used with an internal shaft, to either guide the
part or to pull (rather than push) a load.
