Different Piston Rod Diameters are approved
for various Bore Sizes by the the ISO (International Standards
Organizations) VDMA 24-562 and ISO 6431 cylinder specifications for
Peninsular's model IMH metric steel air cylinders and model ILM
metric aluminum air Cylinders.
These Piston Rod Diameters, standardized by the VDMA 24-562 and
ISO 6431 cylinder specifications, are one
contributing factor that allows cylinder interchangeability to
occur between cylinder manufacturers who produce their cylinders
to Metric guidelines. The dimensions for Piston Rod Threads are also
determined by the VDMA 24-562 and ISO 6431 cylinder specifications and are selected for each approved
Piston Rod Diameter.
The Peninsular Piston Rod Diameter and Rod Thread Chart below
illustrates the cylinder bore, rod diameter and rod threads set
forth by the VDMA 24-562 and ISO 6431 cylinder specifications
which are incorporated into all Peninsular model IMH metric steel
air cylinders and model ILM metric aluminum air cylinders. Know that larger diameter
piston rods reduce the cylinder force on the retracted (pull)
stroke of the cylinder more than smaller rod diameters. This is
because there is less surface area of the piston available.
Should additional Rod
Diameters or Threads become necessary Peninsular will manufacture
these sizes as well; however, adding additional Rod Diameters or
Threads other than those charted herein, could prevent Metric
cylinder interchangeability from occurring to other cylinder
manufacturers.
Our Cylinder Configurator creates models starting at 32 mm bore up through and including
320 mm bore sizes for Peninsular's model IMH metric steel air
cylinders and model ILM metric aluminum air cylinders. For
larger bore sizes - contact Peninsular.
