3. Seal types and numbering system
This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.
Sealing principle: Since there is an oil film controlled by the oil seal edge between the oil seal and the shaft, the oil film has fluid lubrication characteristics.
Materials used
Advantages:
– Very good fitting stability avoiding pop-out of the seal
– Modern lip design provides low radial forces
– Superior radial stiffness, especially for very large diameters
– Cost effective for expensive elastomer materials
– Suitable for use in combination with axial seal

Choosing the right oil seal
What are oil seals?
• Fluorine rubber

Choosing the Right Oil Seals:


One of the primary advantages of natural rubber gaskets is their excellent sealing properties. Due to their inherent elasticity and compression set resistance, natural rubber gaskets can effectively conform to irregular surfaces, creating a tight seal that prevents fluids or gases from leaking. This is especially important in industries such as automotive and aerospace, where even the smallest leak can lead to catastrophic consequences.
Put a wood block at least 6 in. (150 mm) square and 1 in. (25 mm) thick as a spacer between the jack and the sump to prevent damage.
