Piston seal maintain sealing contact in sliding motion between the piston and cylinder bore. Differential pressures acting on the piston to extend or retract the piston rod can be in excess of 400 bar (5,800 psi). The pressure acting on the piston seal increases contact forces between the piston 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 either side) seals.Item
