GYN Rod Seals

Function and Usage
GYN Rod Seal is a single action compact type lip seal. When it is static, the sealing effect is played by the interference compression of the two sealing lips.When it is dynamic, the system pressure is applied at the valley of the Y type seal, which increased the contact stress of the seal lip, piston rod and groove bottom diameter, with the increase of pressure, the contact stress also increases correspondingly, which plays the role of dynamic sealing. Since the GYN Rod Seal do not have an ancillary lip, while low pressure its friction is lower than the GY Rod Seal. GYN Rod Seal is mainly used in heavy load walking machine, piston rod and plunger which are under static pressure, and so on..
 
Advantage
--Good sealing effect, wear resistance
--Good ability to adapt the changes of the pressure
--Impact resistance, suitable for harsh conditions
--Simple design, and easy to install
--Standard components for standard mounting grooves
 
Material
Standard usage
Material: polyurethane  Our Material Code: P902
Back UP Material Code: T600
 
If the working condition is under high temperature, we suggest to use FKM, Our Material Code: F900
 
If the working condition is under high pressure, we suggest to use POM, Our Material Code: S805
 
Technical Data
Working Pressure: ≤40MPa
Speed：≤0.5m/s
Working Temperature：-35℃ to +110℃ 
Working Medium: Hydraulic oil, emulsion, water
 
Clearance

Working Pressure /MPa		5	10	20	30	40
Maximum Clearance E	d＜60mm	0.40	0.30	0.20	0.15	0.10
	d≥60mm	0.50	0.40	0.30	0.20	0.15

 
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.
