Happy with stock bearings?
Hi everyone,
While I keep waiting for my first 3D printer (MK3), I've been reading as much as I can to be ready when the printer arrives. One of the things I saw in this forum is that some people decided to change the stock bearing for others like Misumi or similar brands. I wonder how common is this. This post is for those of you that decided to NOT replace the stock bearings.
1) How did the stock bearing work for you? Do you see a reason for replacing them?
2) Did you do anything else besides oiling the smooth rods, greasing the lead-screws and greasing the bearings?
BTW, I was planning to use what I have that is 3-in-1 oil and Lucas Oil (white lithium grease).
Thanks for sharing your experience/input

I replaced the stock bearings on my previous printer (Anet A8) with the igus drylin bearings. They are much quieter and are a drop-in replacement.
So I built the MK3 with the same. They deform a lot easier so you have to be extra careful on how tight you screw in the u-bolts / E-axis back. Too tight and they deform and grab onto the rods. I did try the original bearings on the Y-axis but just baulked at the noise (just sliding back and forth without the motor attached).
In my case the self-test would set home in a weird place, making the XYZ calibration fail. Backing off the screws on the E-axis back.
I wouldn't replace the bearings in the X-axis mounts (for Z axis), they don't move very fast so never really make noise. They are also under a bit of pressure due to the nature of the holders, so the igus bearings will just deform and grab the rod.

For me the stock Bearings worked very well.
Theres no need to replace them.
But i was a bit interested in what the alternatives would work like.
So i bought some Igus Bearings and replaced the Z and Y Axis.
No differenz on Z. Except somewhat more "slacky".
But not worth mentioning.
On the Y Axis the Igus have much more clearance.
You can easily "twist" the heatbed a few degrees.
It did not change anything to the print result, but left some mixed feelings.
Finaly i changed back to stock bearings on Z, and replaced X and Y with Misumis yesterday.
They fit very very good without any side clearance.
