Telescopic sliding rails are components used as functional units for drawers and sliding systems. Globally, they can be fully or partially extended. In some cases, they act as end-of-travel dampers. Nowadays, there are several versions that can be easily adapted to production equipment, sheet metal processing, peripheral components in plant construction, etc.


The telescopic slide is made of metal profiles and slides on ball bearings fixed in the ball cage. It takes the form of a metal rail. In particular, the device guarantees simple, convenient telescopic navigation. Sometimes it consists of internal elements, fixed external elements and intermediate elements. The latter often uses marble for its appearance. In addition, the telescopic slide is also equipped with opening and closing stops. With this arrangement, the device can carry a load of over 1,250 kg sliding over a length of 2 m. In fact, the telescopic slides help to telescope a heavy object around the translational vibrations.

There are different types of telescopic slides for light and heavy-duty applications. For example, a single-extension slide is a cold-rolled telescopic drawer slide with 2 beams. These comprise inner and outer contours, which are connected by ball-bearing cages. The stroke of these versions can be up to 75%. In terms of length, they can vary from 200 mm to 700 mm.

The load capacity of this ball bearing slide can range from 35 to 91 kg. These slides are mainly used for kitchen or bathroom drawers and office furniture. Also of note is the complete extended slide, which consists of 3 configuration files, including internal configuration files, central configuration files and external configuration files.

Also worth considering is the telescopic spherical slide, which comprises 4 beams and has an inner profile, an outer profile and two median profiles. All these elements are connected by a ball-bearing cage. This can reduce the sliding movement of equipment. They can be used for heavy-duty work, with load capacities ranging from 28 to 289 kg.


There are numerous industrial barriers on the market, and their choice depends not only on the work to be carried out, but also on the needs and expectations of the users. Unidirectional extension slides, for example, are distinguished by their unique two-way movement. In fact, this version allows simple and very practical movements in two different directions.

Slides with full bidirectional extension also allow movement in two directions. Load capacity thus plays a very important role in slide selection. Its change depends on several factors, including slide type, length and the relationship between extended and closed length. You also need to take into account the number of cycles the slide has to complete.

Today, slides can be used either dynamically or statically. The characteristics of the slider and its installation also affect the material’s load-bearing capacity. The slide is generally installed on its side. As far as extensions are concerned, users have several choices for drawer slides. The 3/4 extension part (drawer part) remains in the cabinet.

The drawer is allowed to open the full extension of the entire length of the runner, while the raised part allows the drawer to open beyond the full extension.
