We do the full refurbishments of Trunnion Roller Assemblies in house. When it comes to the Mill Trunnion Roller assemblies, we can do everything from machining all new SG 60 and BS 3100 A1 castings to manufacturing and machining of new Roller and Trunnion shafts. At Lutinsi Engineering we use specialized welding processes and consumables for repairing old SG 40 castings on the assembly. In order to reduce the amount of jet wear resulting from the milling operation, specialized wear liners are installed.
