The Osborn CA is an array of brush roll systems that can be utilized for cleaning, deburring, and conveying. They are constructed with hollow shafts for internal cooling in heavy duty applications. These components use centrifugal force to rinse the brush form inside out, especially in cases where it is being utilized in highly-corrosive mediums. The coolant is continuously guided towards the contact area between brush and work piece surface. In addition, their temperature is maintained in a low range, to increase service life and replacement intervals which in turn delivers minimal downtime.
