PROPERTIES



SHAFT SPEEDS AND LIP MATERIALS

An important consideration when selecting the lip material is the shaft speed (measured in rotations per minute),circumferential speed (measured in feet per second),and shaft diameter(measured in inches).These conditions determine whether or not a given elastomer will operate properly.
The graph below offers general guidelines for determining the compatibility of silicone.fluorocarb
-on,polyacrylate and nitrile with specific shaft and circumferential speed.For more information,ple
-ase contact with us.





METAL CASE AND SPRING
The other major components of an oil seal are the metal case and garter spring.
Below lists the material specification MKS uses of its components.
There are basic types of seals:

1)      Static Seals:
The function of a static seal is to creat a barrier between non-moving surfaces. Typical examples would be a valve cover gasket or O-ring.



2)      Axial Mechanical Seals:
These are face type seals in which the sealing contact is between radially mounted components. One is usually stationary and seal contact pressure is applied by a spring mechanism.



3)      Dynamic "Radial"Seals:
A dynamic radial seal creates a barrier between surfaces in relative motion. One is usually stationary while the other rolates.The cross-section shown below identifies the most common parts of a shaft seal.
