The construction of furniture, storage equipment, garages and small building structures often involves the presence of guide rollers. This element provides the ability to conveniently move the object without harm to its foundation and flooring. Moreover, there are different approaches to the manufacture of such elements, taking into account operational features. Thus, casters for a cabinet require a smooth ride, and models for gates must withstand mechanical loads.
Where are the videos used?
The main scope of such accessories covers furniture production. The small size, reliability and accuracy of the layout are just those qualities that are appreciated by manufacturers of tables, wardrobes, sofas and armchairs. The presence of rollers in the design of such an object makes it convenient to move it, control doors and drawers. And this applies not only to home furniture, but also to professional equipment. In particular, guide rollers are used as part of storage racks and commercial technical support. Separate categories of such devices involve manufacturers of door sections. Such models of rollers are distinguished by more massive sizes, increased wear resistance and a gentle effect on the floor covering.
Furniture castors
Furniture items are equipped with rotary fixed mechanisms, as well as wheels with a brake. For each of these systems, special rollers are used. So, to complete the complete fixation of the object in one place, devices with locking the wheel and the rotary mechanism are used. But this does not mean that the videos remain immobilized forever. Through simple manipulations, the user can unlock and move the furniture. According to this principle, guides for sliding wardrobes operate in the equipment of which sliding bearings or ball elements are used. This arrangement allows you to save the operational resource of the working parts of the cabinet and at the same time make the piece of furniture more functional and practical. However, the wheels can be different and the higher their durability and more stable ride, the longer the main object will last.
Door castors
Depending on the characteristics of the door structure, its fittings may have guides with a different number of gutters. In addition, such mechanisms are divided according to the principle of location, not to mention the division into radial and direct devices. Sliding door compartments on casters usually provide a lower arrangement of guides into which the canvases are integrated. The upper rails in this case only adjust the vertical arrangement of the sections. As for the mentioned number of grooves in the guides, in most cases it corresponds to the number of movable flaps in the span.
For sliding configurations, guides with one trough are used, since their sections move in the same plane. In one set, doors on casters can be complemented by lower and upper rails. The peculiarities of such systems include the fact that they serve the work of just two paintings, and not just one leaf, as in the classic design. At the same time, sections in normal operation do not pass into each other's working areas.
Rollers for sliding gates
As part of the wheels for the gates, the so-called end or rolling rollers are usually used. This removable elements that are fixed to the guide profile. In addition to the beam travel, such wheels provide smooth closing of the wings. Present in the overall design of the running gear of the sliding gate is an additional roller with a plug, which eliminates the ingress of dirt, snow and other foreign elements into the guide mechanism. It is important to emphasize the operational characteristics that distinguish the rollers for sliding gates already in standard versions. Such parts have high indicators of wear resistance, temperature protection and, of course, a considerable margin of safety. These qualities are determined not only by the materials of manufacture, but also by structural elements - in particular, it may be the presence of stiffeners and side stops. Depending on the design of the gate, the system may also include the addition of the undercarriage in the form of lateral rolling limiters, as well as special catchers for soft wheel fixation.
Models with an internal holder
Models of this type are recommended for use in cases where increased loads are expected. Usually these are rollers, the diameter of which varies from 6.2 to 25 cm. Provided that the accessories with the clip are correctly installed, the guide can withstand an axial load of about 215 kN. With high wear resistance, such designs are easy to maintain. In particular, guide rollers with an inner cage can be easily dismantled and replaced. The thread and sizes of the mounting points have a standard format, which makes such rollers universal in use. However, this does not at all eliminate the need for individual selection of a roller for a particular chassis.
Axle rollers
Such models have diameters ranging from 2.6 to 20 cm. In small support systems, they use two sets of single row ball bearings. Large elements of this type are used in tapered roller bearings. Modifications with increased strength indicators are also suitable for use in console and standard mechanisms. All trunnion guide rollers are also available on the market with eccentric elements. Such models are usually marked with the letter "E" in the description of the video. The advantages of such devices include the possibility of vertical movement along the cam, during which constant interaction with the rolling surface is maintained.
Which material is preferable?
Of course, there is no universal material from which the rollers could be made for different fields of application. In the production of office furniture, for example, polyamide and polyurethane elements are used. Such products retain the optimal characteristics of the contact layer, and at the same time, sufficient strength is ensured. For home furniture, beech guide rollers are usually used, which, in addition to technical and physical qualities, are distinguished by their external attractiveness. It is important to understand that monolithic devices for such purposes are practically not manufactured - the combination of a solid base and an elastic external coating of rubber or the same plastic is considered optimal. Of course, storage equipment and gates require casters with higher load resistance. In this case, high-tech polymers reinforced with fiberglass are used to complete the objects. The most durable models are made of steel, which can withstand loads of more than 1 ton.
Mounting rollers
If the installation of the guide rails themselves is carried out without difficulty with the help of special hardware, then the rollers can be completely non-separable. But there are exceptions to the rules. For example, in the supporting mechanisms of sliding wardrobes, experts consider the lower rollers a weak spot. The fastening function in the rollers is performed by screws, latches or flags, which are fixed in the corresponding holes. But it is important not to confuse these elements with regulators. For dismantling, you only need to remove the non-working element of the hardware and install a new one in its place. In this case, the replacement of the guide roller must be accompanied by adjustment. In the case of the same wardrobe, it is usually necessary to adjust the gap between the wall of furniture and the door with the help of landing screws.
Conclusion
In the choice of furniture and its operation, accessories are not always noticeable. Usually, only decorative elements are distinguished, and details with a practical function are left without due attention. Guides for furniture doors, which are hidden in the working rails, but at the same time carry out very responsible tasks, are just such elements. Failure of this accessory can make an entire cabinet unsuitable for use - at least in such situations you cannot do without repair. Equally important is the role of guide rollers in mounting structures, gates, racks and other mechanisms. Careful care of this hardware will extend the life of its components and increase the working life of the main facility.
