Telescopic Rails & Linear Guides for Catering Equipment

Where telescopic rails and linear guides work in catering

Typical mounting points across the industry — the tag shows which product line does the job.

Telescopic rail

Combi-oven & baking racks

High-temperature slides bring rack trolleys and trays fully out of the chamber.

Telescopic rail

Refrigeration & freezer drawers

Full-extension drawers at −20 °C with greases that stay smooth in the cold.

Telescopic rail

Worktop & appliance pull-outs

Heavy mixers and slicers stored below deck, presented at working height.

Telescopic rail

Banquet & serving trolleys

Slide-out shelves and warming-drawer mechanisms in front-of-house units.

Telescopic rail

Food-truck & catering vehicles

Vibration-proof drawers and equipment trays for mobile kitchens.

Linear guide

Automated kitchens & dispensing

Stainless-steel ball guides run the handling axes of automated dispensing, portioning and robotic cooking systems.

What the application demands

The engineering constraints that drive series selection — and how Veltork answers them.

device_thermostat

Both ends of the thermometer

The same drawer hardware family has to work beside the oven and inside the freezer. VT families (except rubber-stopped VT-S at +80 °C) run −20…+170 °C, with temperature greases on request.

Daily chemical wash-down

Degreasers and sanitisers strip ordinary finishes. Zinc-nickel, nickel or E-coat plus stainless balls keep telescopic raceways sound and FDA greases keep them food-compliant; linear guides are available in stainless steel.

scale

Real payloads, small frames

A loaded GN-rack pull-out weighs like machinery. Per-pair capacities and closed torsion-resistant profiles carry it without racking the cabinet.

Recommended series

Start with these series; the configurators weigh your exact load, stroke and service life against the whole range.

Frequently asked questions

Can the rails run inside an oven?expand_more

VT-P, VT-X, VT-O and VT-L are rated to +170 °C with high-temperature greases available. For duty directly in the baking chamber we review the thermal cycle and recommend the execution; VT-S (rubber stops, +80 °C) stays outside the hot zone.

Are the slides food-safe?expand_more

FDA-grade greases are a catalogue option, combined with nickel / zinc-nickel surfaces and stainless balls for wash-down environments — all encoded in the part-number suffix.

Do the slides still run smoothly at freezer temperatures?expand_more

Yes — the range is rated to −20 °C, and cold-specific greases keep pull-out force low so drawers don't stick at temperature.

What extension do serving drawers achieve?expand_more

Full 100 % extension is standard for VT-O, VT-X and VT-S; VT-S one-way can reach 130 % on request so containers lift out vertically without fouling the counter.

Are linear guides available for food-processing areas?expand_more

Yes, for axes inside automated kitchen and dispensing equipment: rails and carriages are available in stainless steel or hard-chromed and nickel-plated, with end seals as standard. The lubricant is agreed per application — ask our engineers.
