Description
The PSH piston seal type is similar to the PSA type, but it has an acetylic resin wear ring to mitigate
possible misalignments and avoid extrusion.
A RR retaining ring made of thermoplastic resin prevents seal ejection during the cycle inversion.
The proposed material is a C0-type polyurethane with high modulus of elasticity, low compression set
and high abrasion resistance. The wear ring is made of a R0-type acetylic resin reinforced with
fibreglass.
Compound reference PSH: CR
The retaining seal is made of thermoplastic resin, R2 type.
Compound reference RR: R2
Avoid all cutting edges and flash on the piston where the seal is housed.
A lead-in chamfer in the groove will facilitate the piston insertion.
Lubricate the seal before installation. For further information please refer to the installation instructions on page 26.
