@snacks as in ball transfer units? i went with the expensive bosch-rexroth ones for my trackball… surprised i even found a place that would sell those in quantities smaller than 10000 units
@snacks they are not properly lubricated from the factory. you need to clean and add proper lubricant
@snacks did you clean it with a good solvent that gives you 10 types of cancer upon eye contact?
@snacks took a very thorough cleaning and a lot of spinning (under a bit of load) to get mine running smoothly
