Hydraulic Cylinder Seals
Common types of Piston Seals
PCAA robust compact double acting seal assembly designed specifically for one piece pistons. It uses a nitrile sealing element which has proven itself in service to be extremely wear resistant and capable of working most effectively in a wide variety of medium duty applications. The seal is also suitable for two piece piston applications.
MAX. OPERATING CONDITIONS:Temp. range : -30°C to +100°C (Up to +200°C on request)
Pressure : 350BAR
Speed : 0.5 m/s
APPLICATION:Light to medium duty cylinders. Static load holding (boom lifting to hold hydraulic platforms) Compact cylinders
COMPATIBILITY:Mineral oils, Water soluble & Water glycol fluids
PCQPCQ seals are constructed from polyurethane and NBR. The assembly of a PCQ piston seal is relatively straight forward because the material is elastic and the seal only needs a small housing. Although useful but not essential, lubricate the seat and the gasket using the same fluid as in the system or a chemically compatible lubricant.
MAX. OPERATING CONDITIONS:Temp. range: -30°C to +100°C
Pressure bar: 0 to 250 BAR at 60°C
Speed: 0.5 m/s
PCRA robust compact double acting seal assembly suitable for one piece pistons. Fabric reinforcement with high mechanical strength, optimum thermal stability and lubricating properties. The small radial dimension of this type of seal, together with anti-bearing / anti-extrusion rings enable them to be assembled onto one piece pistons.
MAX. OPERATING CONDITIONS:Temp. range: -30°C to +100°C (Up to +200°C on request)
Pressure: 350 BAR
Speed : 0.5 m/s
APPLICATION:They are intended for use where housing space is at a premium and in semi severe application. Straightforward and quick to assemble.
PEEDouble acting NBR piston seal for one piece pistons, incorporating Polyester anti-extrusion rings & POM bearing rings.
MAX. OPERATING CONDITIONS:Temp. range : -30°C to + 100°C (Up to +200°C on request)
Pressure : 350 BAR
