Bisphenol Also, Viton has the widest range of resistance to chemicals. It’s resistant to several chemicals like silicone oil & grease, mineral & vegetable oil, aliphatic, chlorinated hydrocarbons, methanol fuels, and so many more.
- Regular inspection and timely replacement of worn-out oil seals are essential practices in rotavator maintenance. Neglecting this can lead to severe consequences, including loss of productivity, increased repair costs, and even complete machine breakdown.
Standard springs are made of carbon steel. We use stainless-steel springs for our GR and GRST oil seals made from FKM rubber. In some rare cases, an O-ring is even used as a spring element. Standard PTFE lip seals are not fitted with springs.
- 4. Remove the cylinder head bolts and carefully separate the cylinder head from the engine block.
If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.
As earlier said, oil seals perform some functions that ensure the functionality of mechanical equipment and extend their lifespan. And how they do this is by retaining lubricants at all cost and not making them escape no matter how high the pressure of the machine is.
Sealing of lip type seal is normally a result of an interference fit between the flexible sealing element, usually augmented by spring pressure and a shaft. Fluid retention is based on the precise amount of lip contact pressure. In most lip seals, increased fluid pressure in the sealed area causes lip contact pressure on the shaft to increase.
Metal case The metal case provides rigidity to the seal, helping it settle on the housing securely. It also ensures easy seal handling and mounting.
ACM
Most oil seals are designed to support very low-pressure (8 psi or less) applications. If at all, there will be additional pressure along the way, pressure relief should be put into play. This is why it’s important to know the characteristics of the oil seals you are considering and compare them with your application.
The sealing lip of the RST-D is more heavy-duty, so it can cope with pressures of up to 10 bar at slightly lower rotation speeds.
1. Pressure: Many oil seals are used in high-pressure applications, so understanding the working pressure of your components is very important.

Imperfections on the shaft
O-rings, which are also referred to as oil seal rings or oil ring seals, are designed to join two parts and ensure that no air, moisture, or gas is allowed to pass through. They are usually inserted into a groove and manufactured to resist pressure. The resistance is what stops foreign elements from entering or leaving the joining.
Is the seal you need not available from one of our standard ranges? No problem. We design and supply seals in any material, size and quantity - from very small to very large volumes.
However, rubber-cased seals do have limitations. For example, during installation, shear stresses can build up between the seal and housing wall, causing the seal to release itself.
