BACK-UP ROLL WITHOUT PIVOT
Tapered roller-back up bearings in inch dimensions are mounted on sheet metal leveling
machines operating under very heavy working conditions. Their design is suitable
to bear big axial loads together with big radial loads.
They are supplied for complete units ready for the assembling and produced in normal
precision class. On request, the outer diameter can be manufactured with cambered
or cylindrical shape.
The revolving spherical roller bearings (execution in mm or iches) can be mounted
on metal flattening machines in rare cases.
This type of bearing can adapt, during the working phase, thanks to its oscillations,
to the possible coupling irregularities between work roll and back up bearing.
After the customer’s request, C.R. evaluates the possibility of manufacturing the
pieces, by considering the quantity and the dimensions.
The series of back-up rollers without pivot is manufactured with two or more full-complement-cylindrical-roller
rows; they are separated by spacers obtained entirely on the outer ring. These bearings
are particularly used on machines that work continuously and in extremely tough conditions,
because of their high dynamic and static load capacity. These spacers between the
rolling raceways guarantee the bearing of the axial thrust.
