Sendzimir mill bearing, Back-up Roller bearing - (Replace FAG)

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 back-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 axial forces that are transmitted to the stand via the adjacent construction.

Back-up rollers Multi-roll cold mill stands are described using different terms  depending on their type and manufacturer:

■ 12 and 20 roll stand

■ Z-High.

■ S-High.

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 back-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 axial 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, running accuracy and surface  quality of the outer ring outside surface of the individual back-up rollers. Back-up rollers

■ are manufactured with restricted tolerances ■ have a running accuracy better than P4

■ are classified in three to seven section height groups each of 3 um to 5 um

■ are suitable for high loads

■ are suitable for high strip speeds, up to 1000 m/min  depending on operating conditions

■ are manufactured in 3 types. These specific characteristics ensure the necessary surface  quality and flatness of the rolled products. As a result, sheet metal can be produced economically to very fine  thickness tolerances and optimum surface quality.
