Slide ring: Filled PTFE O ring energizer: NBR or FKM * Other material combinations can be customized according to working conditions. |  |
Product Introduction
GSI is a rod Glyd ring in hydraulic reciprocating system. It consists of a teflon seal ring and a NBR or FKM o-ring on the static side.
Characteristics
High temperature resistance Excellent static sealing performance Low friction,no stick-slip tendency High speed operation allowed High extrusion resistance Simple groove design Large extrusion gaps, can be used safely even in dirty media High compatibility, almost compatible with all fluids |  |
Application Suggestion
The GSI seal is particularly suitable for long strokes and for larger piston rod clearances in a wide range of fluid and high temperature applications. For example, bulldozers, excavators, forging presses, ceramic presses, rolling mills, servo valves and other machine tools.
