Single cylindrical back-up rollers (execution in inches)
This series can be manufactured with cages or with full-complement of cylindrical rollers.
This back up roller is particularly suitable to work with high radial loads; thanks to its toughness, it maintains all its primary technical characteristics for a long flattening lifetime.
The entire borders made from the inner ring allow to bear the axial thrusts.
The single back-up roller with cylindrical rollers (execution in inches) has the following characteristics:
The outer ring and the inner ring are manufactured in case hardened UNI 100Cr6/SAE 52100 steel.
They reach hardness degree of 60+2 HRC.
Usually, the cages are made in bronze; in some cases, when the dimensions are small, the cage can be manufactured in press-forged sheet.
The sealing system is highly efficient, because it prevents outer agents (dust, mill scale and humidity) to enter the back-up roller; at the same time it prevents the leakage of grease. Grease lubrication is made through a groove on the inner ring.
Precision class P0. It can be manufactured with precision class P5, on request.
On request, they can be manufactured in stainless steel.
