The present invention provides a roller system for a sliding door, comprising: a base frame fixed to a door; first and second support brackets fixed to a front surface of the base frame and spaced apart from each other at a predetermined interval; an elevating member supported to be able to elevate in a vertical direction between the first support bracket and the second support bracket; a roller supported at the elevating member to be able to rotate; springs installed between the first support bracket and the elevating member and between the second support bracket and the elevating member to give elastic force to the elevating member; and an interval adjusting unit disposed on upper surfaces of the first support bracket and the second support bracket, wherein the interval adjusting unit elevates the elevating unit in a vertical direction to adjust the interval between the roller and a guide rail. According to this roller system for a sliding door, the roller is elastically supported by the spring, so that the roller is supported on the guide rail by elastic force of the spring, thereby preventing the deviation of the roller from the guide rail. Further, an adjusting bolt for adjusting the height of the roller in an upper-and-lower direction is installed at the front surface, thereby easily and conveniently adjusting the height of the roller. |
