The two roller entry guides type CREM 440 have been designed for big sections. They are made of special steel suitable for the most severe and exacting conditions and provide long service life under extreme conditions of impact, vibration, heat and corrosion. The body of the guide is composed of two grooved blocks and a central part that are secured by rods; the bearings of the guides are lubricated by air-oil or grease, and cooling water is sprayed on the rollers and on the static blade. The guide has a centralized movement of rollers that improves precision and speed adjustment. All the rollers are submitted to a heat treatment that improves the resistance to bumps and their service life.
