GF-N round roller profile
Round, smooth Green Frame tube: with a rotating pivot connector at each end it becomes a roller on a bearing. For rollers, chutes and karakuri mechanisms. 0.51 kg/m, 4000 mm bar or cut to length.

GF-N round roller profile: smooth aluminium tube that becomes a roller
A round tube without the grooves of the GF grip surface: with a rotating pivot connector at each end it becomes a roller turning on a bearing. You use it for return rollers, chutes and karakuri mechanisms, or wherever the tube grooves are not needed.
Why choose it
A made-to-measure roller
You cut it to the width you need and with two pivot connectors you get a roller turning on a bearing.
Round, smooth surface
Without the grooves of the GF grip surface: suitable for turning as a roller.
For karakuri
Return rollers, chutes and rotating parts are built with the system's components.
Stiff and light
Moment of inertia 1.73 × 10⁴ mm⁴ at 0.51 kg/m.
Choose it if…
- You need a made-to-measure roller within a Green Frame structure.
- You are building chutes or return rollers for karakuri mechanisms.
- You need a round tube without grooves.
Choose another solution if…
- Parts have to slide over a stationary tube: GF-N sliding profile →
- You need a structural tube with the grip surface for connectors: GF-N profile →
- The rollers have to run in a slot: GF-N profile with C10 slot →

Application example
The round roller profile is used where something has to roll:
- Return and entry rollers in workstations and chutes
- Karakuri mechanisms with rotating parts
- Structures where the tube grooves are not needed
How it becomes a roller
Tell us the width, the load and where the roller is to be fitted: we will give you the cut length and components.
How to assemble the roller
Three steps:
Cut to length
Tell us the roller width: we cut the tube in our workshop.
Fit the pivots
Insert a rotating pivot connector at each end: the tube turns on a bearing.
Fix it to the frame
Fix the two pivots to the Green Frame structure at the height you need.
For loaded rollers we check span and load with you before ordering.
The LeanProducts service
From drawing to finished structure, with a single point of contact:
Design and load calculation
We start from your sketch or dimensions: we choose profiles and connectors and check spans, joints and loads.
Cut to length
We cut the profiles in our workshop to the lengths in the design, ready to assemble.
Kit or assembled structure
You receive the kit with the cut parts and the list of components, or the structure already assembled.
Spare parts and modifications
When the process changes we supply components and new cuts to modify or extend the structure.
Send us a sketch, a photo or the overall dimensions: we will reply with codes, quantities and cut lengths.
