Conicity defects

This defect may be linked to a rollers squewing or non-compliant calibrations. After machining and re-cylindrical shape, an adjustment is always necessary. The cones cause:

  • Unplanned axial stresses (risk level)
  • Poor distribution of loads on the rollers (poor balance)
  • Constraints pushed downstream / upstream on the opposite tire (=> risk of tire squews wear)
