Any updates on this? I’ve recently bought the helical ones and found this thread
By any chance you dont know where to outsource that needle bearing? I just got my hardened steel extruder kit upgrade and that bearing is binding hard even after cleanup and lubrication.
Bought the gears from fysetc based on the (positive?) opinions in this thread. I will send mine back, because the gears are binding. The original ones spin smoothly without any resistance and these ones click.
Yes, my stainless steel gears are helical as well, sadly not hardened.
My hardened gears from bambulab have just arrived and like you said, they are helical.
I ordered mine through their official site to germany. Hardened Steel Extruder Gear Assembly | Bambu Lab EU
