The invention relates to an improved bearing tube sawing machine. The improved bearing tube sawing machine comprises a machine table, a rack arranged on the machine table, a discharging operation opening arranged on the rack, a saw blade used for cutting a bearing tube and a sawing wheel arranged on the rack and used for driving the saw blade; the improved bearing tube sawing machine further comprises a bearing tube cutoff material guide table in butt joint with the discharging operation opening and a bearing tube station stabilization device; and a saw blade guide device and a bearing tube compression device are arranged at the discharging operation opening. The improved bearing tube sawing machine is compact in structure and convenient to use; unstable stations caused in the cutting process of the bearing tube can be effectively prevented; after cutoff is carried out, discharging is stable, smooth and not likely to roll off and fall to the ground; and the cutting face is flat and accurate, the sawing effect is greatly improved, and the labor intensity of workers is reduced.
