Back-up rollers
The bearings for tension levelers are considered back-up bearings.
Compared to the ones used in the leveler/flattening machines, these back-up bearings must handle higher speeds. CR has developed and produced them with both radial and axial cages, according to the different types of execution.
The axial bearings that are used on the necks of the flattening work rolls support both axial load – which is transmitted by the work rolls – thanks to an axial ball, and radial load generated by the yielding of the steel sheet, thanks to the roller/needle cages.
