Help Needed: Bearings Specifications for Nextruder Gears on Prusa MK4S
Hi everyone,
I'm reaching out to see if anyone knows the specific bearings used in the nextruder gears of the Prusa MK4S. After about a year of regular use, one of the bearings has failed, resulting in grease leakage and possible rust formation. When I contacted Prusa support, they mentioned that this is considered a wear part.
I’m hesitant to replace the entire PG set from the PG ring since only one bearing is affected. Ideally, I’d like to replace both bearings at the same time to prevent future issues, but I'm unsure about the exact dimensions or specifications needed.
Here’s a link to a video showing the issue: https://youtube.com/shorts/-nkJ8cQoUsU
If anyone has experience with this or knows the part numbers or specifications for these bearings, your assistance would be greatly appreciated!
Thanks in advance for your help!
