The three pneumatic cylinders we
discuss below are:
- Single-acting
cylinders
- Double-acting
cylinders
- Telescoping
cylinders
Single-acting cylinders (SAC) use
pressure that forms from compacted air. In majority of cases, the extension SAC
cylinders have is very limited due to the amount of space the compacted spring
takes.
Double-acting cylinders (DAC) use
air pressure in order to retract strokes and move in range. Two parts make up
this cylinder, both of which let the air in. One is for outstroke and the
other, in-stroke.
Telescoping cylinders, also known
as telescopic cylinders come in single-acting and double-acting modes. Their
designs allow for much longer strokes and tend to be reserved for uses where
the piston has to face minimal side loading.
