4015.OWST100 (Telescopic Slide) - OWST-100 (670-1750kg) Partial Extension Bi-Directional

The OWST-100 is a rugged slide fitted to extend partially front & rear, which has been designed for load maximisation from a small space envelope. Particularly suited to bi-directional aircraft wing production platforms and airport handling equipment, where access is required front and rear. It has a wide range of applications where torsional strength is paramount. OWST slides can be mounted to operate as a pair from a stowed position when fully extended. This provides 100% full travel as the inner beam traverses through the central position and back out to the rear. The datasheet states this dual extension equal to the slide’s closed length. However, typical usage is 50% travel to the front and rear from the central position when closed.

The OWST-100 is a rugged slide fitted to extend partially front & rear, which has been designed for load maximisation from a small space envelope. Particularly suited to bi-directional aircraft wing production platforms and airport handling equipment, where access is required front and rear. It has a wide range of applications where torsional strength is paramount. OWST slides can be mounted to operate as a pair from a stowed position when fully extended. This provides 100% full travel as the inner beam traverses through the central position and back out to the rear. The datasheet states this dual extension equal to the slide’s closed length. However, typical usage is 50% travel to the front and rear from the central position when closed.

The OWST-100 is an extreme load/duty 50% extension slide (670-1,750 kg/pair). At 550mm, 1 pair has a travel of 275mm in each direction, with a load capacity of 1,670 kg. Constructed from cold drawn steel sections and precision milled ball tracks, the OWST-100 telescopic slide has a excellent level of resistance to shock and vibration when supporting a static load in the closed position. Accordingly this drawer runner is well suited to mounting within vehicles. This telescopic slide offers a compact design for the high load capacity. The slide also has good resistance to applied loads when in the extended position making it an excellent choice for dynamic applications and manually operated systems.

The OWST-100 drawer slide may also be fitted in the minor axis (flat). However, the load capacity will be reduced by 60-80% of the stated loading. It can be supplied with a 70% extension which will reduce the load slightly. Please consult our sales engineers for this no cost option. We do not recommend standard OWST slides on accurate robotic pick & place or high speed shuttles, without factory adaptation and customer in situ testing, prior to committing to production. The slides are limited to operational speeds of <0.3m/s

The production process is ISO9001-2015 accredited. Our steel telescopic slides are manufactured from cold drawn steel C45E+C in accordance with EN 10277. Laser cut ball cages are manufactured from zinc plated sheet metal, and the ball bearings are carbon steel C85 G100 in accordance with DIN 5401. Standard Professional Range steel slides are RoHS & REACH certified to withstand over 1,000 hours corrosion protection, until the appearance of red rust. This is due to the investment made in our own state of the art electrolytic alkaline zinc processing facility. Core steel C45 E+C, with a layer depth of 10-12 microns conforming to DIN EN ISO 9227 neutral salt spray testing. No white rust appearance within 120 hours. No red rust within 1,032 hours.

An individual slide weighs 17.26 kg per metre.

Applications can range from slide-based storage systems, lockers and furniture, through rack mounted electronic components, and onto operational and weapon systems requiring linear movement. If required products manufactured from high grade stainless steel can be supplied offering highest levels of corrosion resistance and low magnetic signatures.


Slides and bespoke sub-assemblies for mounting electronic and other equipment including weapon components on vehicles ranging from lightly armoured personnel vehicles (radio and other electronic components) through to battlefield tanks (internal storage, ammunition handling, slide-out generators and workstations).


Equipment stowage components and systems as installed on fire engines

Slide Drawers

Solid section steel slides lengths from 300mm to 2,000mm for pull-out equipment drawers. Extensions from 50% to 200% of closed length can be supplied, in addition slide systems that offer sequential dual extension with bi-directional travel allowing the drawer to extended from either side of the vehicle. This enables rescue crews to access vital equipment quickly and safely, regardless of the vehicle's orientation to the emergency scene.

Special Storage

Our range of reinforced heavy duty steel slides fitted with additional ball tracks and reinforcing ball bearings are ideally suited for use in some of the more unique applications. Together with a range of slides designed using a rigid "I" beam construction our products offer excellent performance under conditions that may exert high direct and torsional loadings as experienced in such applications as pull-out equipment boards and vertical shelves.


Following extensive testing on selected models our slides are used by the U.K.'s leading producers of complete equipment carriers. These complete tray systems are ready for quick installation, including bespoke mountings for specialist equipment such as auxiliary pumps, tools, hoses and rescue equipment.

Drawer locking mechanisms facilitate quick and safe operation of the equipment carrier, as well as hold the fully loaded drawer securely in position when the vehicle is in motion or at the scene.

Food Truck - Mobile Catering

Whether you have a full side trailer extension to build or a small pull out coffee machine tray from the back of a Vespa Ape, we have the right slide for you. From specialized mobile military deployment catering units to market trader applications, we have the knowledge to make it happen.

We are a privately-owned company, established over 30 years and our slides and tool mounts cover every possible application within the catering and hospitality industry.

Our specialty are bespoke telescopic slides suited to catering trailers and full van conversions.

If you require a light load slide, we suggest using our standard rolled steel or aluminum slides covered in this section, for larger full vehicle conversions up to 2000kg we recommend our cold drawn steel section I beam heavy duty slides. The rigidity and strength of the material used in the manufacture, without use of plastic components, make the slides appropriate for heavy duty usage which demand resistance to shock and vibration.

In addition to telescopic slides project we supply auxiliary equipment to fix pipes or other tools.

Our Fulterer range of slides comply with NSF food grade specifications to allow for installation of our drawer slide in direct contact with food.

Motor Manufacturing Plant

Telescopic Slide and Linear Rail components for lineside delivery and component handling systems

Automated Production Lines

Linear movement components and telescopic slides for use on repetition-intensive automated production lines. Components require a high resistance to localized wear patterns, uniform operating loads and designs capable of working at fast speeds with high accelerations.

Manually Operated

Linear rail and telescopic slide products for component delivery and handling at line-side assembly stations.

The breadth of our product range gives you an unparalleled advantage when engineering solutions for delivery systems that have to accommodate large irregular shaped components or sub assemblies within space restricted line-side delivery stillages.

Correct selection and specification of the slide system will ensure maximization of the space inside the delivery stillage and production efficiency while accommodating the natural variations of manual handling present in a time sensitive assembly environment.

Catering Equipment

Whether you want to slide out an outdoor kitchen or a grill table, even a mini fridge, we have the solution for you.

Mobile Furniture

From slide out seat, sliding bed to rolling out dining table, most of the time campers are creative with their own vehicle design. Sliding Systems provide heavy duty slides to help you turn design into reality, slide things in and out without putting support frame on the ground.

Space Extension

We offer extreme duty slide to support engineers in designing RV/Motorhome slide-out.

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 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 Aluminum T6 section slides, available in load capacities up to 330kg.

Outdoor applications can apply specialist marine grade 316L slides, which ensures long-term functionality.

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.


From heavy duty under-train battery rafts to high-repeat door systems and, increasingly, sliding seat systems, Sliding Systems has products that suit all of these applications

Battery Rafts

Heavy duty specialist slide components for mounting under-train battery rafts. The slides must, like the carriage as a whole, comply with crash testing criteria and, as high speed trains become ever more prevalent, there is an increasing requirement that the slides are able to hold heavy battery sets in position despite large dynamic loads.

Battery bays can also house a corrosive atmosphere over long periods, and therefore careful specification of corrosion resistant finishes are required. The nitration option available on our relevant product range provides this resistance as well as considerably strengthening the surface structure of the slide itself.

To facilitate ease of fitting and maintenance, GSF is able to design bespoke fitting brackets including, for example, positioning pins.

Despite improvements to train suspensions, running with metal wheels on metal tracks also makes vibration and shock relevant issues to consider in slide design. Finally, as battery rafts constitute one of the heaviest loads typically mounted on slides, careful consideration is required to the consequent force required to push-in or pull-out the battery raft and the strength and shock-reduction characteristics of the end stops. These are all critical factors that should direct the slide specification.


The use of telescopic slides or linear rails to mount train doors requires a product able to deal with both the dynamic loads and crash survival criteria that are inevitably relevant to train-based applications. In addition, the components have to operate reliably and with low maintenance requirements over a very high number of repetitions. Doors on underground trains are required typically to open and close up to 20 times an hour day after day over the working life of the carriage.

To withstand such a high level of repetitions, the ball bearings and the associated ball track tracks need to be hardened to resist pitting and corrosion. Cold drawn steel slides also perform better over time, as the slide profile is less prone to long term profile deformation than is the case for cold rolled profiles.


Train operators are increasingly offering adjustable seating in first class passenger compartments. Simplicity and durability are key determinants of which linear rail and slide components will work successfully in ensuring that the seat operates reliably as intended and without a requirement for maintenance activity.
