The optimum design for bellows
is the heat-sealed version. The cover
material and guide frames made from PVC are
permanently joined. The connection
of the bellows material and the guide frames
ensures maximum loading capacity and absolute
tightness against liquids such as cooling or grinding
fluids. For special requirements, e.g. resistance
to temperatures of up to 752 °F (400 °C), stitched bellows
can be used. Heat-sealed bellows can
be manufactured in widths of up to 3 meters. |

We make bellows with round, oval or rectangular (with rounded off corners) cross-sections using a special sewing method. Support rings will be used to meet special requirements and applications. Due to their robust design, these bellows have a long and reliable service life, even under extreme mechanical and dynamic strain. The temperature resistance of these bellows can be increased to approx. 752 °F (400 °C) when using an aluminized fabric. |

End frames
End frames, mostly made from steel
or aluminium, connect the bellows
with the machine. Hennig offers
various fastening solutions for the
adaptation to different bellows and
machine interfaces.
