Product Description

Product Description

Product introduction

 ADVANTAGES

AQ seal is a patented development of 
the proven standard AQ-Seal.
 The particular characteristics of AQ Seal are the 
seal profile with a defined seal edge and the use of two O-Rings 
as energizing elements to optimize the pressure profile and to 
reduce gas permeability

AQ-Seal combines the benefits of a low-friction 
slipper seal with the high sealing characteristics of an 
elastomeric seal by incorporating a limited footprint Seal in the dynamic sealing face. This optimizes leakage 
control while minimizing friction

                              AREAS OF APPLICATION
 

-Mobil hydraulics
 -Cranes
 -Stabilizers
 -Heavy duty suspension cylinders
 -Hydro-pneumatic suspensions for heavy vehicles
 -Machine tools
 -Presses
 -Rolling mills
 -Servo hydraulics
 -Offshore equipment
 - Cylinders with retaining function over longer periods such as 
jacks and support cylinders

Product Parameters

- High sealing effect in applications requiring media 
separation, e.g. fluid/fluid or fluid/gas
 

- Double security through the combination of low-friction 
special materials with elastomer seals

 -Low gas permeation rate
 

- Higher pressure application, higher sliding speed compared 
to AQ-Seal®
 

-Outstanding sliding properties, no stick-slip effect
 

- Diameter from 25 to 700 mm 

Pressure:	Up to 60 MPa with mineral oil   Up to 25 MPa for media with   low lubricating properties
Speed:	Up to 3 m/s with linear movements  frequency up to 3 Hz
Temperature:	-30 °C to +200 °C*  depending on seal, O-Ring and Ring material
Media	Mineral oil-based hydraulic fluids, flame  retardant hydraulic fluids, environmentally  friendly hydraulic fluids (bio-oils),  phosphate ester, water and others,  depending on temperature, seal, O-Ring  and Ring seal material compatibility
