Update: Shrink-tubing around the bearing worked for a short while, but since the tubing is soft it quickly developed a groove and began to slip again.
Still much better than using the bare shiny metal, but I did wind up getting a negative movement on a section of complex infill. Since negative values for R do not seem to work, even setting minimum to 0 I will still get pausing without actual jams/issues on a job.
Next attempt will be to use salt water and electricity to etch the outer rim of the bearing. I have done this with other SS items and the result is usually an even, "frosted" surface. I don't know if this will be enough "texture" to grab the filament or not.
