These seals are made out of a nitrile rubber compound to make for better sealing and compatibility with synthetic oils. Their design has a beaded rubber outside diameter to prevent spring back during assembly and for better overall sealing, and a secondary dust lip keeps out contaminants. They come in ISO 6194 and DIN 3760 dimensions up to 250 mm shaft sizes, and they work in -40 to 212F (-40 to 100C) temperature ranges. They are built for industrial applications such as gearboxes containing grease or synthetic oil lubricants. SKFhttp://rbi.ims.ca/4928-607
