Rollers ovality

This defect has more disadvantages than everyone imagines. Taken with comparators, the measures generate the following remarks:

  • Rollers :  This defect causes a load change at every turn roller. It thus increases the stresses and weakens the bearings. It varies the position of the axis of the tube increases the risk of degradation.
  • Tire : This defect is a cumulation of possible distortion: circularity tire, tire thickness, adjustment under tire, shell defects and tube setting. Novexa machining provides an immediate solution.
