Guide for 23mm shutter strap passage with 608 bearings
cults3d
This guide on bearings 608ZZ (or other 608...) for the passage of the strap of a roller shutter allows to fluidify the pulling (less friction, more pleasant). The location of the holes corresponds to those found in stores (spacing of 45mm) The bearing system is built from the 2 pieces of axis. It comes to slip into the notches provided after screwing the body on the window. Rings allow to create a space between the bearings to have a width of 25mm for 23mm (or 15mm) straps => 25mm corresponds to 3 bearings of 7mm + 2 rings of 2mm (printable ring in the stl attached) For information, I used 608ZZ bearings The version for 15mm strap is available here : https://cults3d.com/en/3d-model/home/guide-pour-passage-de-sangle-15mm-avec-roulements-608
