Product Description

BACK UP ROLLER BEARING FOR SENDZIMIR ROLLING MILL
Multi-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.
