Buffer Hydraulic Gasket Seal
Hydraulic cylinders operate in a variety of applications and
environmental conditions, including exposure to dust, debris or
outside weather conditions.
Wiper seals maintain a seal with the piston rod in both static and
dynamic positions. Without a wiper seal, the retracting piston rod
could transport contaminants into the cylinder. They also help
avoid moisture or particles from entering around the outside of the
Piston seals maintain sealing contact between the piston and the
cylinder bore. The pressure acting on the piston seal increases
contact forces between the piston seal and cylinder surface.
Therefore, the surface properties of the sealing surfaces are
critical to proper seal performance. Piston seals are typically
classified into single-acting (pressure acting on one side only)
and double-acting (pressure acting on both sides) seals.
Rod seals maintain sealing contact in sliding motion between the
cylinder head and the piston rod. A rod sealing system can consist
of a rod seal and a buffer seal or a rod seal only.
Heavy duty applications typically consist of a combination of both
seal types. Rod seals also provide a thin lubrication film on the
piston rod that lubricates themselves and the wiper seals, helping
to prevent corrosion of the piston rod surface.
