Recently, the interest in the development of Oilless bearings, which is a kind of sliding bearing, has been attracting to industry. Oilless bearings are mainly used in areas where fluid lubrication is difficult to apply because of large contact area. The purpose of this study is to develop products with higher load and durability compared to the conventional oilless bearing. For this purpose, the optimal steel sheet was obtained and the porosity evaluation was carried out by evaluating bronze sinterability for various steel sheets. The conclusion obtained is as follows.; It was found that steel plate suitable for bronze powder plate is SPCC CR (Cold Rolled). The average porosity of KAG-23, KAG-23G and PBF-8 specimens was 16.8%, 17.8% and 22.1%, respectively, indicating that the porosity of PBF-8 specimen was the highest. As the number of rolling increases, the surface porosity decreases rapidly.
