Telescopic rails for aerospace & defense

Every gram on board is budgeted, and everything that moves has to keep working under vibration, temperature swings and decades of duty. The VT range delivers full-extension access at the best stiffness-to-weight ratio in the catalogue.

Where telescopic rails work in aerospace

Typical mounting points across the industry — each one a sized, catalogued VT configuration.

flight

Cargo-hold & cabin modules

Full-extension slides for stowage modules, crew-rest units and cargo accessories.

restaurant

Galley inserts & trolley bays

Slim rails run ovens, drawers and standard units inside tight galley envelopes.

memory

Avionics & electronics trays

Racked LRUs extracted for test and swap with repeatable, play-free travel.

build

Ground-support equipment

Tool trays, test-rig drawers and maintenance platforms on heavy-duty sets.

rocket_launch

Launch & test infrastructure

Instrumentation pull-outs and umbilical mechanisms on preloaded rails.

security

Defense vehicle & shelter systems

Slide-out racks, workstations and weapon-accessory stowage — shock-rated.

What the application demands

The engineering constraints that drive series selection — and how the VT range answers them.

scale

The mass budget rules

Structure that moves is structure that weighs. VT-X's I-beam intermediate maximises stiffness per kilogram, keeping full extension inside the weight budget.

vibration

Qualification-level vibration

Equipment must stay seated through engine and gust spectra. Zero-clearance standard and K1 preload eliminate play; external end stops secure fast or automatic motion.

device_thermostat

Unheated bays, hot zones

From cold cargo bays to equipment bays near bleed lines: −20…+170 °C rating with temperature greases and finish options to match.

Recommended VT series

Start with these families; the configurator weighs your exact load, stroke and length against the whole range.

Technical fit

Range-wide execution options relevant to this industry.

Lubrication
Medium lithium grease; re-lube every 100 km or 6 months. FDA, cleanroom, marine & temperature greases on request.
Load basis
Telescopic series per pair of rails · VT-L per carriage

Frequently asked questions

What makes VT-X suited to airborne installations?expand_more

Its I-beam intermediate member delivers the highest stiffness and capacity per added kilogram in the range, so full-extension access fits inside a flight weight budget. Capacities are quoted per pair of rails.

Can the slides be qualified for vibration environments?expand_more

Zero-clearance running is standard and K1 preload removes residual play; we provide the mechanical data (materials, masses, capacities, moments) needed for your qualification campaign and recommend external end stops for automatic motion.

Are traceable materials and documentation available?expand_more

The rails are cold-drawn, induction-hardened steel with documented coatings; material and finish declarations for airworthiness or defense-standard paperwork are provided on request.

Do you supply non-catalogue lengths and hole patterns?expand_more

Yes — custom lengths (within the family's ball-cage step), hole patterns and finishes are regular special orders; the configurator or an inquiry with your envelope gets you a part number and 3D model.
