The two roller entry guides type CRE 230 have been designed in two parts with the possibility to replace the central thickness in order to include various type of products, flats and profiles. The guides are completely made of steel, which is then treated to get special anti-corrosive characteristics. A strong point of this type of guide is greater stability of the product than a normal guide, even keeping lesser overall-dimensions. The rollers are individually adjusted through eccentric pins. All the rollers are submitted to a heat treatment that improves the resistance to bumps and their service life.
