摘要： A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body (1) is supported in outer sliding rail bodies (2-1, 2-2) through three rows of support ball bearings (3-1, 3-2, 3-3) which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings (3-1, 3-2, 3-3) are respectively limited within a length range of the outer sliding rail bodies (2-1, 2-2) via ball retainers (4). Each of the outer sliding rail bodies (2-1, 2-2) includes a bottom plate (21), a first side wall (221) and a second side wall (222) which are respectively located at two sides in a widthwise direction of the bottom plate (21), are integrally formed with the bottom plate (21) and extended in a lengthwise direction of the bottom plate (21). The first side wall (221) includes a first arm and a supporting part (2211) which is bent inwardly and extends horizontally from a bottom end of the first arm. The second side wall (222) includes a second arm and an arc-shaped part (2221) which is bent inwardly from a bottom end of the second arm and integrally formed with the second arm. The three rows of support ball bearings (3-1, 3-2, 3-3) are respectively located within an upper inner corner end and a lower inner corner end of the first side wall (221), and the arc-shaped part (2221) in a cross section of the outer sliding rail bodies (2-1, 2-2); and connection lines of centers of the three rows of support ball bearings (3-1, 3-2, 3-3) form an equilateral triangle in the cross section of the outer sliding rail bodies (2-1, 2-2). This sliding rail can solve the problem of insufficient bearing capacity in the existing three-rows-of-ball bearings sliding rail, and can meet installation space requirements for a hidden sliding rail.
