TRACKBALL BEARING, ROLLMASTER

This RollMaster bearing set brings back the smooth, floating glide of a fresh bearing setup. Each unit holds a precision bearing that rolls with the trackball, cutting friction so the ball moves lightly with very little effort.

Bearings don't rub the ball surface the way fixed supports do, so dust and skin oils build up more slowly and your trackball stays smooth longer between cleanings. Swap them in when your current supports feel worn, or switch over from ruby supports for a lighter feel.

Each pack includes three bearing units and a removal tool, enough to replace a full set in a couple of minutes. They fit ELECOM trackballs with removable support units, including IST, IST PLUS, IST PRO and HUGE PLUS.
