Y-Axis Belt Seems Loose

Hey everyone!

Having an issue that has been blocking my use of this printer for a very long time. Used it perfectly fine for many months and through very large prints as well.
The belt that connects the y-axis motor to the y-axis rod seems to be loose.
This causes jumping and just absolutely destroys prints.

Here is a Google Drive link to a video. (Had to put a space in order to not get flagged, don't get mad at me please mods.)

Of course the x-axis shown first has absolutely no play in it when moving, but the y-axis belt has so much in it.
Yes everything is loosened on that rod while I was trouble shooting but it's even worse when everything is tightened down.
Help! This has been driving me nuts and it's been a lot of late nights to even narrow it down to this point and I think I'm stuck.

 

I finally got some time to sit down and work on this for a while. I want to make a note about your quick guide. There are actually 10 screws I had to remove, two additional near the stepper motors.

Now onto why this is a much larger issue than either of us thought.

I got it apart and to my dismay I find a lot of fine grain particles, no idea what it is but it is all over the printer and down into the everything on that side and down behind the wire cover.

It appears as if the bearing (I'm calling it a bearing because that's what it looks like, if that's not what it is please correct me) to hold the y-axis rod on the motor side in place and allow it to rotate freely just disintegrated.

If you check the link I posted in the previous post you will find many pictures I thought should be included and a single short video describing my issue (in the 'Second Post' folder).

I can see and compare the bearings for the y-axis to each other and they are just entirely different. One has all of it's components and off sets the rod just fine so it's not loose, the other doesn't do this (as is shown in that video).

I believe the pieces are all there for the bearing but just apart. The inside ring is stuck on the rod and the other pieces fell out and I eventually discovered they're for the actual insides of the bearing (I believe).

Is there a possibility to get a new one of these bearings or anything like that? I don't feel like this is supposed to happen after about 6 months of moderate-heavy use or even ever! Anyone have any idea what may have happened to this bearing or if it's possible it'll happen to others?

 

Do you know where I can get the specific ones used in the construction of the R2? They seem a little of an odd one..

(Had to do the link thing again.. 3 posts have been made though)

Folder link is the folder with all of the pictures and the video, bearing link is just for one of the bearing pictures.

 

Ok, thank you. Just hoping I can get one soon.

 

Thanks for the link fix.
It is indeed that bearing.

 

I'm looking into what you gave me and I can't seem to find a flanged one. Of either size, going to get exact sizes soon.

EDIT: I only have inch calipers and I measured approx. 8mm x 12mm. The flange is about 13.5mm
Exact measurements:
ID: .313 in. = 7.9502 mm
OD: .464 in. = 11.7856 mm
Flange: .534 in. = 13.5636 mm

Second EDIT: Height measured approx 3.6 mm
.144 in. = 3.6576 mm

 

Does anyone know if I can get one under warranty or something like that?

 

Hi everyone, just coming back to conclude the story. I was able to get a new set of bearings via Robo. After disassembling it and replacing the exploded bearing, I got it back together and did some tuning to get it back to printing properly and it's working just fine.
