Abstract
The present study describes applicability of edge crowning to improve tribological properties of journal bearing for reciprocating compressor for home appliance products such as refrigerator. A roller burnishing was applied to the edge crowning. The Iribological properties were evaluated with a developed apparatus using the actual component of the journal bearing system. It was found that the crowing was effective means to stabilize the friction coefficient. In addition, the significant increase of the anti-seizure load was obtained on the both edge crowned bearing. The deep grooves resulted in the seizure was formed on the bearing surfaces. The position of the groove was different depending on the crowning condition.
