In regards to improving friction you could try roughing up the rollers a little? --- End quote --- Yes. Oil is in the bearings, only. Everything has been wiped with alcohol. I already used 400 grit sandpaper on the rollers. I guess I'll try courser sandpaper but they were not rough to begin with. I don't have anything to compare to... Are trackballs smooth and shiny or should they also have a texture? |

No the ball should be smooth and shiny. |

I roughed up the rollers with a 300 grit Scotch-Brite pad and used a 2500 grit pad on the ball. That seems to have helped. Only once did it slip but not nearly as bad as it did before I roughed everything up. I'm hoping that was just a hair on the ball. I did notice a couple of small hair-line cracks in the ball. They are very hard to see and you can barely feel them with your fingernail. Do these balls develop cracks? This thing has seen very little use over the years. |

I give up! I have taken this POS out dozens of times. The last thing I tried was to blast all oil out of the bearings and put a couple of drops of Tri-Flow in each bearing to reduce as much resistance as possible. The ball still slips on the rollers. Is there any difference in the bearings sold by SuzoHapp and these: https://pgnbearings.com/products/r4-zz-ball-bearing-1-4x5-8x0-196?_pos=1&_sid=9e105a536&_ss=r The bearings from SuzoHapp come lubricated with the same thick grease that needs to be replaced with oil, correct? |
