GFI Piston Rod Guide Rings

Function and Usage
GFI Piston Rod Guide Ring plays a supporting and guiding role to the piston rod, which can bear high load, with low wear, and other characteristics.The special design structure makes the installation more reliable and stable. It is mainly used for heavy load condition.
 
Advantage
--Good pressure bearing capacity
--Inclined slice design is easy to install, and also, with high stability
--Low friction coefficient of material, long service life
 
Material
Filled Polyoxymethylene Delrin (POM)   Our Material Code: S802
 
Technical Data
Working Temperature：-55℃ to +225℃ (Temperature refer to the material)
Speed: ≤1m/s  
Dynamic Pressure:≤75N/mm² (60℃)
Working Medium: Mineral hydraulic oil, emulsion, water and other media
Tips: The operating limit to the load and temperature is maximum. In the actually usage, due to the interaction of work parameters the maximum must be lower.
 
Installation
Groove: Closed
In order to avoid the damage of the seals, during the installation, the seals should be leave away with the shape edge of the parts and tools. The sharp edges and burr in the installation area of the seal must be removed. The special design of GFI guide ring requires a high fitting surface tolerance for the components.
