POM extruder bearing kit + U-shaped guide arm compatible with Titan Aero Sidewinder X1 X2 Genius Prusa i3 MK2 4max pro Chiron metal extruders

This idler arm is improved with a U-groove bearing, replacing the older version with a smooth-surface bearing. A groove in the middle prevents filament from slipping easily during printer operation. The large gear is made of POM and stainless steel, both machined with high-pressure CNC machining. The teeth are sharp, uniform, and have a longer lifespan, resulting in more stable and smooth filament feeding. Used for 1.75mm filaments. Compatible with the original Titan extruder, the Titan Aerodeuse extruder, Prusa i3 MK2, Sidewinder X1 X2, the Genius printer extruder, Anycubic Chiron, 4max Pro, and Sovol SV01 D. Contents: 1 gear, 1 idler arm assembled with grooved bearing.
