SC type seals (Also commonly called R21 seals) are one of the most commonly used types, they have a rubber-covered outside diameter with a single sealing lip on the inside diameter. The SC types feature a garter spring which allows some give to prevent a build-up of friction. (Seals under 5mm width may not always feature a spring.)
