Abstract: This paper pointed out the primary property requirements based on the clear analysis of the working condition of a rock bit bearing system.The results obtained show that the super hard materials are adaptable to rock bit bearing than metal materials.Better structure designs and machinable-mixed bearings are the strongest rival in the future rock bit market.

Key words: rock bit, abrasion-proof material, wear resistance, material
