Bearings Curiosity

Sovol SV06 Plus

A question on Drylin bearings.

The bearings on my sv06 Plus were very noisy on receipt, so I lubed each bearing with lithium grease which cut the noise significantly. Wanting to further reduce bearing chatter, I installed Drylin bearings.
Absolute quiet on the x and y axis but encountered a problem in the x axis in the extruder assembly was very tight when moved by hand with the power off. The y axis was fine. This resulted in some failed prints until I reinstalled the original ball bearings that came with the machine. I think the Drylins just had too much resistance, making the drive belt skip. Now all is working as it should.
Has anyone else experienced this? The Drylin’s are 10mm just like the rods and are super quiet on the y axis. I’d like to seem the same on the x axis but not at the expense of failed prints.

One of my relationships made the same observation.
He installed this type of bearing to eliminate noise, but after a few weeks, he reinstalled the original bearings because the stepper engine was getting too hot.

The normal plastic only drylin bearings are not meant as replacement for the metal ones. They need precise tightening, they are too loose without but can bind up quick with rod misalignment.
You can try printing holders for them that can be tightened and set up for good alignment.

But you can try instead the metal-shell polymer bearings like these, they are more of a replacement for the ball bearing types.
