GYT Rod Seals

Function and Usage
GYT Rod Seal is a lip seal which are designed with one main lip and one ancillary lip. 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. A little of oil slick is arranged between the main and the ancillary lip, which effectively prevents the dry friction and the premature wear of the seal. GYT Rod Seal is mainly used in heavy load running machinery, the 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

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.
