The FlexFit system is tested to 100,000m travel with an 80kg load under normal conditions and the carriers show no sign of play throughout the service life. The stainless steel rails 1529S and 1537S can be supplied in single lengths up to 3,994mm. Please contact us for minimum batch quantities. 

The rails are supplied in zinc plated steel or stainless 430 (1.4016). The carriers are supplied only in stainless steel and are interchangeable. There are no plastic parts used in this system, so it is suitable for high temperature environments. Unlike other systems, the rails can have customer specific mounting options and hole patterns subject to minimum order quantities.

Type 430 stainless steel has good corrosion resistance to a large variety of media including nitric acid and some organic acids. The corrosion resistance of type 430 is optimal when it has a highly polished surface. As with other ferritic grades, resistance to stress corrosion cracking is very high. Being ferritic, the 430 rail will have magnetic properties not associated with grade 304

FlexFit is a highly economical solution for low to medium load linear motion. The steel rails and stainless carriers are now shipped out same day despatch.

Following thorough research in house and at our manufacturing facilities we can offer a slide which is particularly suited to aircraft seating. The full aerospace range is fitted with cross roller bearings, due avoid any effect of brinelling.

The 5220 Radial Slide (140-154kg/pair) is made from high strength aircraft allows which has be rigorously tested to outperform standard ball bearing models.

The T6 aircraft grade aluminium beams have milled race tracks for tolerance. The surface finish is black hardened anodised as standard, other finishes are available on request.

The cross-roller bearings are made from precision hardened steel and chromed rods, it is possible to fit them with Delrin if the project requires light weight, performing slides.

7075 -T6 aluminium provides a high strength material, commonly used in aircraft fittings with a Rockwell A hardness 53.5 and an ultimate tensile strength of 572 Mpa.

The 450mm length with a 480mm travel has been independently (cyclically and abuse) tested to 60,000 cycles with a 100kg load, passing all criteria for aircraft seating use.


Furniture & Architecture

We are delighted to be able to advise our customers on the most diverse projects possible.

One day we could be talking to an ambitious DIY customer who wants to install a removable console tray in his game room and the next project could be a whole building interior refurbishment destined for micro flats. Whilst each project represents different challenges and requirements we are confident in finding a suitable slide or linear rail.

Standard furniture fittings will suit the Thomas Regout or Fulterer range of rolled steel slides and linear rail. Whereas high end architectural furniture design may call for aluminium drawer slides, such as the 8027/8028 or the aluminium T6 slide from our professional range.

To suit yacht interior design, we can supply Viadana chandlery and stainless steel 316L telescopic slides.

Industrial Storage

In-rack drawers and bespoke storage systems and assemblies

Museum Storage

The breadth of GSF's product range gives you an unparalled advantage when engineering solutions for unique storage systems that have to accomodate large irregular shaped artifacts or exhibits. Our experience with some of the more unusual high volume low load applications and environmentally sensitive storage conditions is available for you to call upon together with access to perhaps the widest range of sliding procuts in the world.

Correct selection and specification of the slide system will ensure maximisation of the space inside the storage or display unit while providing safe and secure access when required.

Workspace Storage

GSF offers a wide range of standardised products that are available direct from stock and which are most suitable for use in workspace desking, tool storage, assembly and operation stations. These products can be purchased free of restrictive minimum order quantities and charges.


Linear slide systems are designed to support and transfer loads over distance and an be used for either horizontal or vertical movements.

Internal Doors

Linear Rail is generally the preferred component for mounting internal sliding doors.

Machine Building

The design and construction of speciialised operational machinery and machine guards. The excellent range of Saibo hardened linear rails are designed to be economical whilst offering exceptional service life required in machine guarding.


Specification and design of linear movement systems incorporating linear rails and telescopic slides for use in machine guarding applications and the design and installation of manufacturing, cargo handling and other situation specific plant and machinery.

In such industrial applications, reliability and robustness are key requirements. When incorporated into automated plant, movement precision is also vital. The load capacities indicated on our high-end range represent the maximum load that can be carried whilst causing a slide deflection at full extension of no more than 1% of the slide's closed length. This is a much higher and more rigorous standard than is typically used by others for measuring slide load capacities, as a results our customers have come to rely on Sliding System's products for their durability and strength.

Our range also includes slides that operate with ultra-high precision based on innovative roller bearing technology, and which are self aligning.

Our design team has the ability to offer all or any of these components when working alongside your own engineering team.

RV & Motorhome

Shop Fitting & Display

The retail sector is increasingly becoming a shopping ‘experience’ therefore the fittings for such outlets are vital to fit the bill. With our full range of slides, we can help you achieve both design and functionality.

Our lighter duty slides are well suited for smaller drawers or applications where little load is applied when extended. If the project requirements are to move a wall from its original position to display goods a bottom mount slide might be more suitable due to space restrictions. The Fulterer Range of vertical pull out slides provides stability, load capacity as well as the sleek design required in current retail outfits. All slides in the Fulterer range are available in different finishes (white, grey and black) which can be supplied against MOQ’s.

Special & Commercial Vehicles

Our telescopic slides and tool mounts cover even the most demanding project for commercial vehicles. Smaller, lighter duty rolled steel or solid section slides from our General Devices range will suit a keyboard tray or a display screen, whereas cold drawn steel section slides will fit requirements for full vehicle extension such as mobile broadcast vehicles carrying several 1000kg’s.

With over 30 years of experience, we are more experienced than any other supplier and manufacturer to be able to advise of suitable and performing products.

Sliding Systems are an approved supplier for many prestigious and well-regarded manufacturers both in the United Kingdom and abroad.

With our flexible production facilities, we can accommodate any project and are pleased to assist with special requests whenever possible. Applications involving shock and vibration call for heavy duty, cold drawn steel section slides which we are also able to supply in 316L marine grade stainless steel. If weight or corrosion resistance are parameters that are important we suggest Aluminium T6 section slides, available in load capacities up to 330kg.

Outdoor applications can be fixed in place with specialist marine grade 316L hooks, which safely hold tool boxes or vehicle covers in place.

Response Vehicles

Roadside assistance and other categories of vehicle that need to stow and provide easy access to equipment can be enhanced through appropriate use of telescopic drawer slide and linear rail systems.

The twin requirements of operator safety and operational effectiveness are of paramount importance. GSF's ability to select and adapt from an unrivalled base product range, and its ability to assist with the design of bespoke and space-saving drawer systems enable us to make a significant contribution to your own product design.

Yachting - Marine - Non Corrosive

The need for storage is not confined to land structures, every seaworthy structure requires a multitude of pull outs or heavy-duty generator tray. We can offer the widest range of stainless steel 316L telescopic slides and non- corrosive tool mounts.

For interior fittings we suggest 304 stainless steel slides, larger heavy-duty applications are covered with our specialist bottom mount General Devices D1050/D1054 slide. The latter allows the user to look a generator tray in the opened and closed position. Bottom mount slides are useful for applications where space is limited thus a traditional drawer slide installation is not suitable. The poxy coating offers some corrosion resistance but achieve full corrosion resistance, we suggest stainless steel 316L which can be supplied upon customer request.

Our full professional range DTS is now available in marine grade stainless steel 316L which includes the end stops and ball cages. With low profiles starting from 40mm up to profile height and lengths up to 2000mm we are confident to be able to supply a complete range.

As a distributor of the prestigious yacht and boating equipment manufacturer Viadana SRL, we are also able to support your yachting project with their full chandlery range.
