ZURCON WYNSEAL

Description

The Zurcon Wynseal is a double-acting seal consisting of a special polyurethane seal ring and an O-Ring as energizing element.

The particular characteristic of the seal is the special design of the seal edge profile. Two external seal edges act as primary seal for pressures from both sides and prevent any build-up of hydrodynamic pressure over the seal profile and the risk of the blow-by effect. The central back-up and sealing bulge increases the sealing effect*. Grooves are provided on both sides on the plane surfaces to provide activation of the energizing O-Ring. These ensure direct pressure loading of the seal under all operating conditions.

Since the installation groove is identical to that for the Turcon Glyd Ring, the seal is ideal for the standardisation of cylinder construction if, efficient and low cost seal elements are demanded in large quantities and, the cylinder can be adapted to meet different operating conditions. It has to be taken into consideration that in this case the gap dimension has to be checked !

Advantages

– High static and dynamic sealing effect
– High abrasion resistance
– Simple groove design, one-piece piston possible
– Suitable for grooves to ISO 7425, Part 1.

Only from PW42 and the following Series No.; PW40 and PW41 without sealing and supporting bulge.

 

Application Examples

The Zurcon Wynseal is the recommended sealing element for double acting pistons of hydraulic components in various sectors such as:

• Machine tools
• Forklifts & handling machinery Agriculture
• Industrial hydraulic light to medium duty

Technical Data

pressure:                        Up to 25 MPa (Z20N)
Up to 40 MPa (Z05N/WUAGN)

Speed:                            Up to 0.5 m/s

Temperature:              -35qC to +110qC

Media:                           Mineral oil-based hydraulic fluids

Important Note:

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.
