- The Crucial Role of Oil Seals in Motors
- Firstly, the 20% refers to the typical rubber content found in high-quality oil seals. This compound, usually a blend of synthetic rubber, contributes to the seal's flexibility and resilience. It enables the seal to maintain its shape under varying temperature conditions, from the cold rigors of winter to the heat of heavy machinery operation. The rubber also provides the necessary sealing force against leaks, preventing oil from escaping and contaminants from entering the system.
Extrusion and Nibbling

Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.
In addition to the installation procedure, our specialists and suppliers would also like to draw your attention to some cases that occur around oil seals.
Installation inaccuracies
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.
