Abstract: Compact structure, large carrying capacity, stable operation, long working lifespan and low friction power consumption are the advantages of hydrostatic journal bearing, which is applied widely in diversified mechanical equipment. This paper researched the key part of framework aclinic slide structure on diamond flame sawing machine, which is the axially moving hydrostatic journal bearing. The major sawing motion form of diamond flame sawing was analysed. The structure designing model of the bearing according to the practice was established, and by the systemic analysis and research on the lubricating mechanism and performance, the designed scheme was proved out. The results satisfied the demands of practical application.
