Zusammenfassung:	The utility model relates to a cylindrical roller thrust bearing for machine tool main shaft, mainly comprising a bearing race (1), a bearing shaft washer (2), a cylinder roller (3), a bearing cage (4), a main shaft (5) and a bearing seat (6). The bearing cage (4) is provided with a flange. When the axis line of the bearing is arranged horizontally, a certain guiding clearance is arranged between the diameter (d1) of the flange and the diameter (d2) of the bearing race (1). The utility model has the beneficial effects that the main shaft guiding for the bearing cage can be changed into the bearing race guiding, and therefore the tearing of the cage to the machine tool main shaft can be reduced.
