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
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
