 PTFE O-Ring |
 |
|
|
The ptfe o-ring is processed with cutting . It improves the
defects of rubber o-ring and leather material .Because of heat-
resistance ,include chemical- resistance, oil- resistance ,
heat -resistance , it can be used widely.
It has the excellent resistance for organic solution including
high- temperature, ozone,oxygen ,mineral oil,composition hydraulic
solution , fuel , chemicals.
maximum using pressure : 300kg/§²
maximum using temperature : -70~260¡É
use : semiconductor equipment , mechanical
seal , pump, diaphram , gasket , inspection equipment , washing
equipment etc. |

|
 no lubrication
The lubrication is pured for the metal ring in order to reduce
wear and coefficient of friction, and the carbon ring have been
used with water . But it doesn't need to use lubrication due
to ring of non-oil supply and non -water supply which has a
abundant self lubrication. |
Strong for a impact
The carbon ring is damaged by light impact during handling and
assemblage.
But it is safe. |
|
No corrosion
It is not eroded by fluid or gas . No adherence and pollution.The
teflon of low coefficient of friction among solid materials
is less motor load at the begining of operation. |
Caution for purchase and design
The size is decided with change of material according to temperature.
It should be under permitted limit of load for rider ring .The
gap of cylinder and piston is considered with expansion at time
of driving
Consider how to remove the heat . The surface temperature of
ring should be less than
200¡É |

| B
: Step cut type |
|
using with A type after particular
processing for maintaining adhesion with Espander Ring |
| C
: Angle cut type |
|
using for specialize conditon
in case of high pressuere of using fluid or gas |
| The above type is used for overlapping two

| Back-up Ring |
|
|
|
This is the production for improving durability , include
function ,heat- resistance.
It prevents scratch ,pushing out ,eccentricity |
| The shape which is cut with a slant lineis standard but no
cutting shape can be used unless there is the problem of installation.
