PISTON SEAL MA11

STANDARD SEAL DIMENSIONS

DESCRIPTION

The MA11 seal type is specially designed for heavy duty applications. When the coupling clearance between bore and piston cannot be reduced and the pressure is very high – above 250 bar – the MA11 seal type, thanks to a strong anti-extrusion ring, is among the most appropriate of seal types.

TECHNICAL DATA

Pressure: < 400 bar at a temperature of 60° C Speed: < 0.5 m/s Temperature: from - 35° C till +100° C Fluids: mineral oils

MATERIAL

The

MATERIAL

used for the seal is polyurethane at 93 Shore A with high elasticity module. The anti-extrusion ring is made of acetylic resin reinforced with fibreglass and with high tensile strength.

ASSEMBLING

The

ASSEMBLING

of this seal is done in semi-open groove. The anti-extrusion ring should be installed after the seal. It is important to remove any flash or cutting edge on the piston not to damage the seal during the overlapping.
