CR 28

The four roller entry guides type CR28 are made of a specially developed steel, suitable for the most severe and exacting conditions, and provide long service life under extreme conditions of impact, vibration, heat and corrosion. 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. All the rollers are submitted to a heat treatment that improves the resistance to bumps and their service life. The guides are particularly suitable for a better stability of products such as stellar-square, dogbone and special steels, to avoid a possible movement of the profiles in the channels of the cylinders. The guides have independent and centralized movement of the roller holders through a cam.
