What are the structural characteristics of a skeletal seal?

What are the structural characteristics of a skeletal seal?

The cylindrical shape of the oil seal’s outer surface ensures a static seal for the internal cavity. The rubber outer edge of the internal metal skeleton, together with the exposed edges of the metal skeleton, are designed for skeletal sealing. Most applications require polishing and electroplating with anti-corrosion coatings. The twisted spring-loaded sealing lip accommodates shaft movement, while the enhanced structural design of the sealing lip improves the stability of the static seal, thereby enhancing overall sealing performance.
