The invention relates to a slide for a linear guide which has the slide and a rail element with two running surfaces facing each other. The slide has a main part and a plurality of rolling bodies, and the plurality of rolling bodies are received on the main part such that the plurality of rolling bodies can roll at least on the two running surfaces or carry out a sliding movement relative to the two running surfaces. The main part defines the position of each one of the plurality of rolling bodies in a pull-out direction relative to the main part, wherein the slide additionally has two slide elements and a spring element, and each of the two slide elements is mounted on the main part such that it can move in a vertical direction perpendicular to the pull-out direction so that each of the two slide elements can be brought into frictional engagement with a respective running surface, the spring element being supported on the main part such that the spring element biases the two slide elements away from each other in the vertical direction.

A ball bearing slide includes: two outer slides, an inner slide located in the outer slides, two ball cages, and ball rows rollably arranged in the ball cages and supported between the inner slide and the outer slides; wherein the inner slide includes two end parts and a connecting part connecting the two end parts; the ball rows are located between the end parts and the outer slides; the outer slides drive the ball rows to rotate in a pull-out direction and a push-in direction; wherein each of the end parts of the inner slide has a free end; the free end of at least one of the end parts projects towards a centerline of the certain ball row to form a stopping part. During operation, the stopping part prevents the ball rows from falling off from the inner slide under excessive force.

A ball bearing slide (100) includes: at least one outer slide (1), an inner slide (2) located within the outer slide, a ball cage (4) located between the inner slide and the outer slide, and three rows of balls (3) rollably arranged in the ball cage; wherein the three rows of the balls (3) includes a first ball row (31), a second ball row (32), and a third ball row (33) located between the first and second ball rows in a vertical direction; wherein the inner slide includes a first curved part (24) against the first ball row, a second curved part (25) against the second ball row, and a third curved part (26) against the third ball row; the third curved part is located between the first ball row and the second ball row in the vertical direction, and is symmetrically arranged relative to a symmetry axis of a line connecting centers of the first ball row and the second ball row. With the first, second and third curved parts, internal space of the ball bearing slide for containing the inner slide is increased, which rationalizes the ball cage arrangement and optimizes the ball bearing slide design.

A slide rail assembly includes at least two slide rails. One of the two slide rails includes a pair of walls and a middle wall connected between the pair of walls. The middle wall of the slide rail is arranged with a predetermined part bent relative to the middle wall, and the predetermined part is formed with a ball groove.

A ball bearing slide includes: at least one outer slide, an inner slide located within the outer slide, a ball cage located between the inner slide and the outer slide, and three rows of balls rollably arranged in the ball cage; wherein the three rows of the balls includes a first ball row, a second ball row, and a third ball row located between the first and second ball rows in a vertical direction; wherein the inner slide includes a first curved part against the first ball row, a second curved part against the second ball row, and a third curved part against the third ball row. With the first, second and third curved parts, internal space of the ball bearing slide for containing the inner slide is increased, which rationalizes the ball cage arrangement and optimizes the ball bearing slide design.

A carriage for a linear guide system. The linear guide system includes a rail member including two running surfaces facing each other, and the carriage movable relative to the rail member in and against a pull-out direction. The carriage has a base body, a first pair of support elements and a second pair of support elements in the form of sliders and at least one first support spring element and at least one second support spring element. The second pair support elements is arranged spaced apart from the first pair of support element in the pull-out direction. Thereby, each of the sliders of the first pair of support elements and each of the support elements of the second pair of support elements is movably mounted on the base body in an upward direction perpendicular to the pull-out direction, such that each of the sliders is frictionally engageable with a respective one of the running surfaces. The at least one first support spring element is mounted on the base body such that the at least one first support spring element biases the sliders of the first pair of support elements away from each other in the upward direction. The at least one second support spring element is mounted on the base body such that the at least one second support spring element biases the support elements of the second pair of support elements away from each other in the upward direction.

An embodiment of the present invention provides a sliding device comprising: a first rail member which is open at one side surface thereof; a second rail member which slides on the first rail member and is open at one side surface thereof; and ball members which are disposed between the first rail member and the second rail member such that at least three ball members are provided as seen in a cross section, wherein the first rail member and the second rail member are arranged to be engaged with each other through the open side surfaces.
