GF-N triple roller for curves
The basic module for gravity roller track curves: three rollers in an aluminium and POM body. By connecting several modules with the couplings you get a curved roller track that carries containers from one lane to another without pushing.
Why choose it
Custom curves
Join as many modules as you need to cover the arc of the curve.
Fixes to the pipe system
Mounted on the Ø 28 mm structure with GF-N connectors.
No motors
The container runs by gravity even round the curve.

Application example
The chained modules form the roller track curve:
- Changes of direction: you take containers from one lane to another
- Compact layouts: curves where a straight roller track will not fit
- Gravity karakuri: paths that turn without motors

Join the three-roller modules with the curve roller couplings until you cover the arc you need; with the single-roller module you close the curve or adjust its length. The modules are fixed to the Ø 28 mm pipe structure with GF-N connectors. Send us the radius and angle of the curve: we will calculate how many modules are needed.
With GF-N connectors for Ø 28 mm pipe, or by using the module's side slot. We will specify the connectors based on how the structure is built.
We check the transition between curve and straight on the project, based on the roller track you use and the slope: send us the layout and we will propose the solution.
Yes. Green Frame profiles can be ordered as 4000 mm bars or cut to the length you need: we do the cutting ourselves, in our workshop. Give us the dimensions of the pieces or send us a sketch of the structure and we will prepare the cutting list.
Yes. The standard series is GF-N (Ø 28 mm pipe); GF-S (Ø 19 mm) is lighter and more compact, GF-G (Ø 43 mm) is for stiffer structures. There are mixed connectors that join pipes from different series, for example a Ø 19 or Ø 43 pipe to a Ø 28 pipe, so you use the right diameter at every point of the structure.
No. The connectors are fixed to the pipe with hex socket screws: a hex key is all you need. Loosen the screw, insert the pipe, bring it into position and tighten. No welding, drilling or painting.
Yes, it is the strength of the pipe system: loosen the connectors, move or replace the pipes and retighten. You can raise a shelf, extend a workbench or reuse the components in another structure when the process changes, with continuous improvement in mind.
Yes. We can design the structure (workstation, flow rack, trolley, line-side supermarket) with the load calculation and deliver it to you assembled or as a kit with the parts already cut and the list of components.
No. Profiles and connectors are in anodised aluminium: the surface resists corrosion and wear without painting and is easy to clean.
Yes. The range includes conductive components such as ESD inner end caps, ESD clips for electrical continuity between pipe and connector, and ESD inserts for levelling feet and castors. Tell us which EPA area you work in and we will tell you the components to use.
