## Description

Package: 1piece idler arm assembled with U groove gear bearing, 2pcs springs

Review: Not exactly perfect for Anycubic Chiron, however it does work. - It doesnt fit the same as a direct replacement would. It wont release the filament simply by pushing the lever. However it works, and it is the hardened version that is compatible with CF better than the plastic stock one. You just simply have to loosen the screw each time you want to remove filament and tighten it back up once you feed it in. This was on an Anycubic Chiron extruder.
Review: Compatibilité X1 ok - S'adapte bien sur ma Sidewinder X1
