Abstract:
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.

Claim (Index 3):
The three-rows-of-ball bearings sliding rail, as recited in  claim 2 , wherein multiple first stop blocks are located at two end portions of the bottom plate of the outer sliding rail body in a lengthwise direction of the ball retainer, and are formed by inwardly punching the bottom plate of the outer sliding rail body.
