The design of the ball guides is quite simple, and the mechanism consists of several main and a number of auxiliary parts. If the first includes metal runners and balls, the second is represented by various locking elements and stops made of both metal and plastic.
Ball guides are more technological, high quality and durable.
They provide the best stability of the sliding systems and ease of use.
To understand the principle of the mechanism, let us turn to the simplest representative of the ball guides. — two-section nonseparable. In this case, there are two so-called rails, differing in size and having a specific U-shape, which allows you to place one part inside the other.
The action of this hardware is based on the mutual movement of durable steel tracks that make up the tire.
Between them (usually above and below) are small balls, resembling similar components of the bearing. In the role of the locking element, preserving the integrity of the structure, a part of the outer rail, at a certain moment limiting the course of the device, acts.
Since the tracks are embedded into each other, such systems are called telescopic.

Depending on the purpose of the intended use, the ball guides can take on different shapes and have a unique set of functions. Most often they are divided by the following characteristics:
Options for mounting vary in different models, and you can choose the necessary types.
Installation can be carried out on the side surfaces of the drawers or in the slots of the side surfaces.
As a rule, the final cost of non-separable mechanisms is somewhat lower than their fragmented counterparts. All due to the fact that the latter require special methods of production of the rail and methods of fixing balls on them, which would allow to disassemble and assemble the device freely without fear of losing small parts.
Strong steel balls move inside the profile, providing a stable easy sliding of the boxes of any material and any size.
The total price of the guides is also influenced by the number of stages provided, as well as the number of levels involved in the system. This happens for a similar reason - due to the significant complexity of the design of the mechanism.
On ball guides often establish drawers in sliding wardrobes.
Despite the fact that the useful properties of telescopic devices have been evaluated in several areas of activity, the main part of such mechanisms is used in the manufacture of various furniture.
The use of ball guides will ensure silent operation, will increase the permissible load acting on the box.
A striking example is the wardrobe with folding bars for hangers, cabinets for shoes and wardrobes with drawers - in general, all those items that can either save space or increase the comfort of living in it.
By installing the ball guides, you ensure the durable, uninterrupted operation of the sliding elements of your furniture.
Ball guides have a positive effect not only on convenience, but also on the efficiency of using furniture. It becomes much easier to clean and get things out, and thanks to free access you can occupy all the useful space of the cabinet.
Among the indisputable advantages of ball guides is the full extension of the drawers.
The most common use of the mechanism is still drawers, which are equipped with all kinds of cabinets and cabinets. It is not difficult to manufacture the listed household items on your own, and the drawing of the future product only seems complicated.
They are virtually silent, have a smooth ride and much better decorative properties.
After all the necessary calculations have been made, and the building itself has been built, it is necessary to switch to the formation of the drawers and the fixing of the sliding device.
The set of ball guides consists of two steel symmetric telescopic runners: left and right, each of which is disassembled into two parts.
With the installation of the latter on your own furniture, there will also be no problems, and before calculating the parameters of the cells, you should choose a specific design of the ball guides. This should be done because different representatives of the mechanisms are of different sizes (first of all, the thickness is different).
The depth of the box should be equal to the length of the guide.
Leave a gap of at least 10 mm between the back wall of the dresser and the back wall of the drawer.
Having decided on a type of telescopic devices, you can proceed to the calculation of the basic parameters of the drawer.
When calculating this characteristic, you can not blindly repeat the size of the case.
The thickness of the outer walls and the thickness of the sliding mechanism must be taken into account.
To this must be added a technological gap that compensates for measurement errors and ensures free movement of components.
Usually its optimal value is at the level of one millimeter.
Thus, the width of the drawer is calculated by subtracting from the same parameter of furniture the doubled thickness of its outer walls, double the thickness of the mechanism and double the size of the gap.
The drawer length is also limited by the available free space.
However, its calculation is much easier - it is enough to reduce the available distance by the size of the next gap.
In the set position, such guides can be adjusted in two planes.
It is necessary to correctly set the position of the box in the box.
As a result, properly adjusted drawers are obtained, on which facades are hung.
In this case, it is selected from the following considerations:
After calculating all the necessary dimensions, you can go directly to the installation of the mechanism.
The technological opening (gap) not only provides the movement of the boxes, but also eliminates any interaction between them.
Screws must be selected so that their caps do not stop the mechanism.
In other words, it is necessary to provide such a distance that the front panels of nearby sections do not touch each other, because this is the main cause of damage to the furniture facade.
The most accurate marking when installing ball guides will avoid distortions of boxes and other problems with the further fastening of the facades.
If the guides are non-separable, then you first need to attach them to the inner walls of the cabinet or cabinet, and only then - directly to the boxes. In the case of a collapsible mechanism, there are no restrictions on this, that is, the installation of the relevant parts can be done in any order.
This instruction will help those who first decided to independently install them for their accessories.
