Sliding hub was initialy made in ductile cast iron GJS-500-7Fatigue failures occured during test phase
Sliding surface induction hardened to 40-50 HRC(~371-475 HB)

ADI 1050 material improved fatigue resistance and wear resistanceNo cost increase because surface hardning is not required anymore
Sliding surface induction hardening not required anymore

Future steps at CNH
ADI will be involved in:- Applications where higher strength is required
and a small build in space is available
- Possible cost reduction program on parts where an additional surface heat treatment is now required- Applications which are suffering from wear- Weigth reduction
All of the new designs are developed with close collaboration with the material engineers- Prototype parts are tested both in a lab and in a field environment- Quality check is done before approving a supplier
