AMS Shaft Bearing Gone

Bambu Lab AMS Troubleshooting
1

I was messing with the AMS and removed one of the shafts. Of course, one of the bearings on the end of the shaft went flying in my shop, and I cannot find it. I know I can buy the entire shaft from Bambu, but does anyone know what size bearing this is so I can see if there is one on Amazon?

Here is the shaft on the Bambu store - https://us.store.bambulab.com/collections/spare-parts-for-ams/products/ams-driven-support-shaft-assembly

here is the bearing. I measure 7.8MM OD, 2.6MM ID and 3.8MM Width

I just stumbled upon this issue via Google because I stupidly lost a bearing on my AMS HT and can’t find it. I understand this post was made and answered well before the AMS2 and AMS HT even existed, but just for future reference:

AMS Driven Support Shaft Assembly: uxcell 693ZZ Deep Groove Ball Bearings (not confirmed on the bambu store page)
AMS2 Driven Support Shaft Assembly: uxcell 693ZZ Deep Groove Ball Bearings (per bambu store page)
AMS HT Driven Support Shaft Assembly: uxcell 692ZZ Deep Groove Ball Bearings (per bambu store page)

I believe on the AMS HT the 693ZZ bearings will not fit the shaft or the plastic cradle correctly, causing the roller to jam or the bearing to pop out again immediately.
