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
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
