ZURCON U-CUP PUA
Description
The Zurcon U-Cup PUA is a single acting piston seal out of injection moulded polyurethane. It is provided with a robust dynamic sealing lip and a wide contact area of the static lip, which guaranties an effective positioning in the groove.
The profile is suitable for pressures up to 40 MPa provided that the extrusion gap is adapted to the pressure level. Thanks to the elasticity of the polyurethane material the U Cup can easily be installed in closed grooves.
Advantages
– Simple groove design
– High abrasion resistance
– Long service life
– Effective sealing effect even with non excellent mating surface finish
Application Examples
The Zurcon U-Cup PUA is the recommended sealing element for single acting pistons of hydraulic components such as:
- Presses
- Lift platforms
- Aftermarket
Technical Data
Operating conditions
Pressure: Up to 40 MPa
Speed: Up to 0.5 m/s
Temperature: from -35_C to + 110_C
Media: Mineral oil based hydraulic fluids
Clearance: From table the maximum value of the radial clearance Smax can be selected for dimensioning the piston. The values indicated in this table must be reduced by 30% when temperature exceeds 80_C.
Important Note: Zurcon U-Cup PUA
The above data are maximum values and cannot be used at the same time. e.g. the maximum operating speed depends on material type, pressure, temperature and gap value. Temperature range also dependent on medium.
