The AQ5 piston seals is specifically designed for heavy-duty applications with large diameters. It is highly recommended as a double-acting piston seal for hydraulic equipment.
Design Description:
The AQ5 piston seal is ptfe seals features a star-shaped ring elastomer with limited contact points on the dynamic sealing surface, enhancing the sealing performance of the moving interface. It combines the low friction characteristics of the PTFE material and the sealing properties of the rubber elastomer, resulting in significantly reduced friction and minimized leakage.
Standard Materials:
Sealing ring: (F-PTFE)
O-ring: NBR or FKM
Star-shaped ring: nitrile rubber (NBR) or fluoroelastomer (FKM)
Application Scope:
The AQ5 piston seal is suitable for applications with high speed, high pressure, and pressure retention requirements. It can be used as a sealing component for double-acting piston accumulators, positional control cylinders, clamping cylinders, etc. It is widely applied in equipment such as machine tools, presses, rolling mills, shoe machines, piston accumulators, and heavy-duty suspension cylinders. It is particularly recommended for heavy-load and large-diameter applications.
