ZURCON COMPACT SEALS
Description
The Zurcon Compact Seal are double-acting piston seals with integrated guide rings . The combination of the elastomer energiser and the polyurethane special shaped sealing element provide excellent sealing effect and service life. The function of the guide rings is to guide the piston in the cylinder tube and to absorb transverse forces.
Type PU DAS
For Zurcon Compact Seal PU DAS is designed without Back-up rings. For easy installation in closed grooves, the combination into one stiff sealing element and one soft energizing element is required. Back-up rings are unnecessary thanks to the high extrusion resistance of the polyurethane material.
Type Polypac EUD
The Zurcon Compact Seal EUD design includes T-shaped Backup/guide rings and a combination of seal ring and energiser.
Advantages
– High wear resistance
– Low compression set
– Optimal leakage control
– Easy installation into closed grooves
– Excellent service life
Application Examples
The Zurcon Compact Seals are the recommended sealing element for double acting pistons of hydraulic cylinders for:
- Truck cranes
- Mini excavators
- Heavy duty cylinders
Technical Data
Operating conditions
