MAS-...
2 Method of operation and application
When compressed air is applied to the con-
nection, the textile-fibre tubing 3 of the
fluidic muscle type MAS-... expands. A tensile
force thereby arises, as well as a contracting
movement in the longitudinal direction. The
MAS-... is single-acting. The movement is
transferred to the work load by means of con-
necting elements as described in the section
"Accessories." These are screwed into the
thread 1. There is an overload protection
device in the connecting flange 2 of the
MAS-... . If the load exceeds a certain level, a
safety valve blows the excess compressed air
down.
The fluidic muscle type MAS-... is designed
for:
– lifting and lowering masses
– transmitting forces (e.g. clamping two
plates)
– use as pneumatic spring.
The MAS-... is simply a pulling actuator which cannot transmit pressure forces and
does not have a guide. The pulling force is at its maximum at the beginning of the
contraction and drops almost linearly with the stroke to zero. Expansion in the
peripheral direction cannot be used for clamping tasks, as friction can damage the
muscle.
