Racks live or die by serviceability: a 60 kg server, a 120 kg battery module or a test insert has to glide out to full depth, hold position dead-still, and go back in — thousands of times, in a 19-inch grid where every millimetre of width is spoken for.

Typical mounting points across the industry — each one a sized, catalogued VT configuration.
Slim full-extension pairs carry heavy servers clear of the rack for top-cover service.
BESS and UPS modules slide out for inspection and replacement — load per pair, not per person.
Repeatable extension for burn-in racks and ATE drawers, with two-way options.
Partial-extension rails present terminations without straining the loom.
Cleanroom greases and nickel surfaces for fab-compatible pull-outs.
Converter and inverter stages extracted under their own busbar weight.
The engineering constraints that drive series selection — and how the VT range answers them.
Between the rack post and the chassis there are a few millimetres. The S-shaped intermediate of VT-S packs full-extension stiffness into the slimmest section in the range.
A rack unit serviced at full extension must stay flat — connectors, rails and technicians all assume it. VT-S is engineered for minimal deflection even fully extended.
Modules are serviced hot: jerks and tipped loads are normal. Zero-clearance running and optional preload keep the unit seated and quiet in transit racks too.
Start with these families; the configurator weighs your exact load, stroke and length against the whole range.
The rack specialist: slim S-profile, 100 % extension (130 % on request), minimal deflection — sizes 28–63 for everything from switches to battery modules.
Partial extension for cable-side panels and drawers where 50–60 % travel is enough and stiffness is everything.
I-beam full extension when module mass outgrows slim slides — best capacity per added width.
Range-wide execution options relevant to this industry.
VT-S sizes 28 and 35 are the usual fit for 19-inch server and test racks — the slim S-profile intermediate was designed for exactly this gap. Mounting-hole patterns and lengths are catalogued per size.
Capacities are quoted per pair of rails and depend on size, length and extension — from tens of kilograms for switch trays to several hundred for battery modules. The per-size tables on each series page give exact C₀rad values.
Yes — VT-S one-way (S1) can be ordered with extended stroke up to 130 % of rail length, carrying the chassis fully clear of the rack frame.
Nickel and zinc-nickel surfaces, stainless balls and cleanroom greases are available on request; the part-number suffix specifies the execution.
Send the payload, stroke and envelope, or let the configurator narrow the range first. Our team returns a sized series, deflection estimate and 3D model — prototypes in under 14 days.
