As type B with dust lip
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.

Oil seal specifications

Scrape off all the traces of dirt and old gasket from the engine and sump flanges with a paint scraper.
Longer seal life can be expected with shafts having a Rockwell (RC) hardness of 30 or more. When exposed to abrasive contamination, the hardness should be increased to RC 60.
Oil seals close spaces between moving or stationary mechanical components to prevent lubricants like grease and oil from escaping, while also preventing dust, dirt, moisture, and other contaminants from entering the seal. Also known as shaft seals, dirt seals, lip seals, or grease seals, the primary components of any oil seal include an inner metal ring, which provides structural support, and a spring, which provides interference for effective sealing.
Today, traditional oil seals have to compete with a new variant oil seal, which is used in most modern engines.
