3 PIECES PISTON SEAL

Compact seals which have a widespread use are used as double acting sealing elements in hydraulic cylinders’ piston applications.

Three-piece double-acting compact seals consist one fabric reinforced elastomeric sealing element, which allows a high mechanical strength, and two thermoplastic guide rings. The set withstands abrasion very well.

ADVANTAGES

  • Low friction, free of stick-slip effect
  • Improved abrasion resistance
  • Good dynamic and static sealing effect
  • Long service life

APPLICATIONS

Mining equipment , iron and steel industry , marine hydraulics andearth moving equipment.

INSTALLATION

Three-piece piston seal profile has been designed for its installation in closed or open grooves taking the indicated catalogue information into consideration. We recommend having open groove design for dimensions that are smaller than Ø50 mm. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

For special applications that require high temperatures ,piston seal set can be manufactured with reinforced cotton fabric + FKM and PTFE guide rings.
