Fork and Damper Oil Seal: These oil seals are designed primarily to be used in areas where the sealing surfaces will slide in and out e.g. Motorcycle fork legs and damper mechanisms, that said they can also be used in applications where the sealed objects rotate.

An oil seal normally consists of three basic components: The Sealing Element (the nitrile rubber part), the Metal Case, and the Spring. It is a widely used sealing component. The function of a seal is to prevent the leakage of medium along the moving parts. This is mainly achieved by the sealing element. Nitrile Rubber (NBR)
NBR is the most commonly used seal material. It has good heat resistance properties, good resistance to oils, salt solutions, hydraulic oils, and gasoline. Operation temperatures are recommended from -40deg Cto 120deg C. It also functions well under dry environment, but only for intermittent periods.

This is a double sealing lip seal arrangement with one primary sealing lip and a dust protection lip.
The seal cases are made from SAE 1008-1010 Carbon Steel and are often coated in a very thin layer of Nitrile rubber to assist sealing in the housing.
The principle function of the metal case is to impart rigidity and strength to the seal.
The spring is made from SAE 1050-1095 Carbon Spring Steel which has a protective zinc coating.
The principle function of the spring is to maintain an even gripping pressure around the shaft

I have never needed a seal and you haven't stocked the size. You don't get better than that
