Clamping
Systems
Application:
Pneumatic toggle clamp with horizontal cylinder
attachment. Equipped with FESTO pneumatic cylinder, double acting,
anodised and interchangeably mounted.
With magnetic piston for
end-position sensing
and throttling ports for dampened speed. The
clamp is galvanised and passivated. The stainless steel rivets run
in case-hardened bearing bushings except for size 1 due to lack of
space. The bearing bushings are greased.
Application:
Can be deployed as single or in-line clamps, can
be controlled independently of each other via machine control.
This relieves the operator from frequent clamping work.
Supplied:
Complete with tempered, galvanised pressure screw.
