The present invention relates to a sliding bearing assembly using a roller bearing. The sliding bearing assembly using a roller bearing includes: a rail (110) fixed to a bed (102); a table (120) partially coupled to the rail (110) to slide with respect to the rail (110), the table (120) having an oil groove (121) with a zigzag shape in the lower wall (120a); and a plurality of first roller bearings (130) inserted into the lower wall (120a) between the oil grooves (121) so that the plurality of first roller bearings (130) are disposed between the rail (110) and the table (120), wherein the plurality of first roller bearings (130) regulate pressure according to the change in weight. Thus, the consumption of additional oil and air may be reduced, and the sliding bearing assembly may adaptively respond to a change in load. In addition, abrasion may be minimized to improve durability, and the hardness of the transfer system may be adjusted. |
