A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body is supported in outer sliding rail bodies through three rows of support ball bearings which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings are respectively limited within a length range of the outer sliding rail bodies via ball retainers. Each of the outer sliding rail bodies includes a bottom plate, a first side wall and a second side wall which are respectively located at two sides in a widthwise direction of the bottom plate, are integrally formed with the bottom plate and extended in a lengthwise direction of the bottom plate. The first side wall includes a first arm and a supporting part which is bent inwardly and extends horizontally from a bottom end of the first arm.

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.

An insertable fixing module of an industrial cabinet rail includes a main body, a hook, a linking slider and a press key, and the rail is installed in the industrial cabinet. The hook is installed in the linking slider. With the design of a slop pushing between the linking slider and the press key, an inverted hook portion of the hook is latched into a latching hole of a frame. In the present invention, the press key is situated on the inner side of the frame to prevent from being touched accidently. During installation, the fixing module can be inserted and fixed. During removal, the press key is pushed along the extending direction of the rail, so that the hook can be withdrawn to remove the rail. The invention improves the stability of installation and the convenience of installation and removal.
