Table 7 shows the shaft design checklist.


J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.
Rubber oil seals have to perform in extreme conditions. Therefore, we accommodate all relevant conditions (mechanical and thermo-chemical phase) to maintain the integrity of the rubber oil seal in these circumstances.
Garter springs are generally used when the lubricant is oil, as it provides the necessary downward force to maintain a tight seal. However, when grease is the lubricant, garter springs can often be eliminated. Due to its low viscosity, grease doesn’t require as much downward force to maintain an effective seal.

Many seals come with a garter spring, found within the backside of the seal. It provides contracting pressure against the sealing surface. Making sure the spring seats correctly within the seal is an excellent first step.
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.
