Development aims
SA253 has better wear resistance and compatible with engines with cast iron shaft.
Development concept
Improved wear resistance through the Si particle coarsening
Improved fatigue resistance by increasing the strength of the aluminum alloy lining
Increment of strengthening components compensates for the decrease of fatigue resistance caused by the Si particle coarsening.
Performance
Resistance wear
Seizure resistance
Shaft material：
Hardened shaft
Non-hardened shaft
Application example
- Connecting rod bearing
- Main bearing
- Crankwasher
