Light telescopic slide rails is an assembly of metal profiles sliding on ball bearings held in ball cages.
It is equipped with stops on opening and closing, and ensures the sliding of loads up to several tons.
They can be used as a drawer slide, hanging rail, door slide, keyboard drawer, handling rail, furniture slide, telescopic table slide, horizontal guide or in some cases, as a vertical guide for a door or as a machine tool guard guide.
Benefits of Light Telescopic Slide Rails
Quick access and space saving
Thanks to these light telescopic slide rails, it is easier to assemble and dismantle certain modules, a significant advantage in the event of an emergency and for maintenance productivity.
01
Discretion and ease of use
With slides, sliding is smooth and continuous. All thanks to a special lubrication system. When they leave the factory, steel telescopic slides are already lubricated with a high-pressure bearing grease and specific grease for stainless steel models. However, it is possible to request specific lubrication such as high-temperature grease.
02
Safety system
Our light telescopic slide rails are sold with stops sized to withstand repeated handling at the rated load. To hold the modules in the open or closed position, you can request an optional mechanical locking system, either internal to the slide (telescopic slides with locks) or external (ergonomic handle with lock).
03
Flexible and adjustable design
Light telescopic slide railsoffer flexibility in design, allowing customization to fit specific requirements and compartmentalization needs.
04
Durability and long lifespan
Constructed with high-quality materials, light telescopic slide railsare built to last, withstanding everyday use and providing long-term durability.
05
Medium Duty telescopic slides:
Our medium-duty systems use higher-grade aluminum to handle operations between 89 pounds and 265 pounds. We offer multiple configurations to meet a broad range of needs.
Heavy Duty telescopic slides:
These industrial-grade, aluminum-coated slides work well for heavier-duty applications between 190 pounds and 980 pounds.
Linear slides
Linear slides feature a short inner member or carriage within a closed track, and are frequently used for applications that are more focused around guidance than access. Linear slides operate more effectively when the load is applied in the centre of the carriage within the slide length. When used in a cantilevered manner, the load capacity can become significantly reduced because of the short length of the carriage and the torque applied.
Caged ball bearing slides
Caged ball bearing slides have of a number of rolling balls between the members, held by a cage, or ball retainer. This keeps the ball bearings within the length of the slide’s tracks and keeps movement smooth. Caged ball bearing slides can typically be used for applications where low movement force is required, such as drawers, arcade penny pushers and vending machines. They are ideal for side-mounted applications, and can also be used flat-mounted, although this will reduce the load rating.
Recirculating ball bearing slides
Recirculating ball bearing slides are designed with rolling ball bearings that circulate infinitely within the recirculating ball carriage in a loop, which allows the carriage to travel any distance, limited only by the length of track.
Materials and components of light telescopic slides
Telescoping slides are made up of an outer rail and one or more inner rails. Designs with longer strokes (equal to the rail length or greater) typically incorporate an intermediate element, which improves stiffness and reduces deflection.
Unlike profiled rail and round shaft linear recirculating linear guides, telescoping slides are offered in a variety of materials—from aluminum or stainless steel to hardened cold rolled steel. Each material offers different advantages in cost, weight, inertia, load capacity, and stiffness. Manufacturers also offer various surface treatments, such as hard chrome or electrolytic zinc plating, to withstand harsh environments.
Telescoping linear guides are grouped into three general categories, depending on their stroke length: Partial stroke, full stroke, and extended stroke.
Partial stroke: The extension length is typically 50 percent of the rail length.
Full stroke: The extension length is equal to the rail length. Full stroke versions may include an intermediate element.
Extended stroke: The extension length is greater than the rail length. (Also referred to as “over-extension.”) For most extended stroke slides, the extension length can be up to 150 percent of the rail length. These designs often require an intermediate element.
The load capacity of a telescoping slide depends on the rolling elements and the rigidity of the intermediate element. In many telescoping guide applications, static load capacity is more important than dynamic load capacity, since the purpose of the guide is to move a load to a position and hold it there, resulting in intermittent, rather than continuous, operation.
Due to their design, telescoping guides have higher radial load capacity than axial load capacity. Therefore, manufacturers often recommend that these guides be mounted on their sides, so that the most significant loading is in the radial direction. The typical design for telescoping linear guides is to use two guides in parallel, with the load centered between the rails.

The light telescopic slide rails and pull-out rails
Light telescopic slide rails and pull-out rails are applied to handle various industrial, trade, and private tasks. They serve as functional assemblies for drawers and pull-out systems for almost an unlimited number of applications. light telescopic slide rails rails are offered in full and partial extension, and it is important to choose the right version depending on the area of usage. Heavy-duty versions (heavy-duty rails) are often utilized for heavy equipment, in industry, in vehicle construction, in a rear extension, etc. light telescopic slide rails rails and extension rails of this type are also a good choice for equipment construction, sheet metal construction, and peripheral assemblies in plant construction.
Full extension vs. partial extension
Partial extension rails consist of 2 rail elements and can be extended by up to 75% of the closed length. Full extensions, on the other hand, have 3 rail elements and can be extended 100% accordingly. Thanks to the longer extension, full extension rails offer better, easier access.
It is a cold roll forming process, which is similar to the roofing product, but requires a higher performance in profile. Types of Product Names of drawer slides vary such as, telescopic channel slides, drawer runner, under mount slide rail, steel ball slide, and ball bearing drawer slides etc.
Major types of drawer slides are 2-section and 3-section, which consist of outer, middle, and inner rail. They are widely used in kitchen cabinet, home furniture hardware, office appliance, and industrial equipment. drawer slide machine Process of Slides roll forming Processes of drawer slides roll forming is a continuous cold rolled steel strip passing through a set of rollers, and then punching, straightening, and cut off to length.
Telescopic Drawer Slide Channel Production Line is provided with straightening mechanism to make sure the material is nicely formed in a predetermined shape to meet the original design.
Telescopic Drawer Slide Channel Production Line Working Flow: Material Coil - Decoiling - Roll Forming - Hydraulic Punching - Cutting - Discharge - Finished Profile. slide machine Customized roll forming lines Every slide rail varies in some detailed design, is capale for providing a customized production line to meet the expected profile.
Lubrication and maintenance:
While light telescopic slide rails rails made of stainless steel or aluminum are delivered ungreased, our standard slides are shipped ready to install in a greased condition. To prevent friction and protect components, a visual inspection should be carried out from time to time, depending on the operating conditions. Dirt particles should be removed and "dry" guideways should be lightly relubricated with a rolling bearing grease. The relubrication period depends on several factors:
- Degree of dirt particles
- Process conditions
- Load
- Operating temperature etc.
Due to the design, moving cages may occur, as the ball cages of the light telescopic slide rails slides are not restrained guided. In this case, it is necessary to move them to the end positions in order to realign them.
Installation of light telescopic slide rails slides
Our light telescopic slide rails slides are almost free of play. Therefore, in order to guarantee proper functionality, they must be installed in an angular and parallel alignment.
The load utilization is optimized by using all mounting holes or mounting threads.
