01

Why long strokes are difficult

With every additional metre of travel, the lever arm and the deflection grow. A long telescopic slide has to stay straight and stiff, run smoothly over its whole length and still carry the load at full extension. That requires precise profiles, careful mounting design and the right number of stages.

02

How FEDS builds long telescopic rails

  • Precision CNC machining and milling of profiles up to 3 m in our own facility
  • Multi-stage and over-extension designs for long travel from a short closed length
  • Deflection calculated for your load, centre of gravity and mounting orientation
  • Functional push/pull testing over the full stroke before dispatch
03

Typical applications

Long telescopic slides are used in rail and transportation, industrial machinery, automated storage, test benches and special vehicles — wherever a heavy load has to be moved out of a structure over a long distance.

Frequently Asked Questions

What is the longest telescopic slide FEDS can make?

FEDS engineers telescopic systems with openings up to 12,000 mm as custom solutions.

Can long slides still carry heavy loads?

Yes, but deflection increases with length, so the load at full extension is calculated for each application. Send us your load case for a recommendation.
