Abstract��On checking carburizing bearing steel ring pieces, there are cracks appeared on some pieces. By means of metalloscopy and Rockwell hardness test, it is showed that massive and network carbide appeared during carburizing process leading to cracking of carburizing bearing steel rings in the first and second quenching period. In the meanwhile, the related preventive measures are also proposed.
