Product Description BACK UP ROLLER BEARING FOR SENDZIMIR ROLLING MILLMulti-roll cold mill stands are described using different terms depending on thrie type and manufacturer : 12 and 20 roll stand .Multi-roll cold rolling mills are used to process high grade steel strip and non-ferrous metal strip .in order to prevent whipping of the work rolls , they are supported by means of intermediate rolls and support shafts .several bak-up rollers are arranged adjacent to each other on these support shafts and separated by support saddles . these allow the requisite distribution of roll load .Depending on their type , back-up rollers can support high radial forces or high radial forces together with acxial forces that are transmitted to the stand via the adjacent construction .The quality of the rolled metal sheet is determined not only by the bending rigidity of the entire support shaft but also the section height tolerance(below 0.005mm) , running accuracy and surface quality of the outer ring outside surface of the individual back-up rollers .Back up rollers bearing are manufactured with restricted tolerances . have a running accuracy better than P4 . classified in three to seven section groups each of 3μm to 5 μm .suitable for high loads .suitable for high strip speeds , upto 1000m/min depending on the operating conditions .manufactured in 3 types .these specific characteristics ensure the necessary suiface quality and flatness of the rolled products . as a result , sheet metal can be produced economically to very fine thichness tolerances and optimun surface quality.Bearing No.Boundary dimensions (mm)Basic load ratings (kN)Fatigue limit loadMass (kg)(kN)d(Fw )DTCrr1CrCorCu
