GBA Rod Seals

Function and Usage
GBA Rod Seal is made of a nitrile rubber O ring and a high strength polyurethane sealing ring. The highly elastic O ring ensures the preload of the sealing lip at the low pressure e or at zero pressure. Sealing performance is influenced by the temperature is very small, even a certain wear of the seal, the preload can also be ensured. GBA Rod Seal is not sensitive to vibration load and peak pressure, and is suitable for harsh working conditions.
 
Advantage
--Not sensitivity to vibration load and peak pressure
--Good sealing effect under low temperature
--Impact resistance, suitable for harsh working conditions
-- Easy to install
 
Material
Standard usage
Sealing Body Material: polyurethane  Our Material Code: P902
O Ring Material:Nitrile Rubber (NBR)  Our Material Code: N800
 
Technical Data
The Standard GBA Rod Seal is mainly used for plunger, piston rod, cylinder, gas drilling, mufti-stage cylinder,  forging machine and the hydraulic equipment for walking equipment.
Working Pressure: ≤35MPa
Speed: ≤0.5m/s  
Working Temperature：-35℃ to +110℃ 
Working Medium: Mineral hydraulic oil, emulsion, water and other media
Tips: Limit value of the above data, can not be used at the same time. The maximum working pressure depends on the type of material, the pressure, the temperature, the gap, and etc.. In actual usage, due to the mutual influence of working parameters, the maximum value setting is lower.
 
Installation
Groove: Both Closed and Opened (Open type groove is recommended for the limit diameter and limit cross section.)
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.
