Befor

Problems by Conventional methods

Manufacturing method : CO2 arc welding
Oil leak from un-welded section
Implementation of 100% air tightness (leak) inspection
Spatter removing process is necessary.

After

Improved effect by IZUMI's Friction Welder

Enhanced air tightness at joining section
Abolition of air tightness (leak) inspection process
Abolition of process of removing spatters from hub's sliding section
