Roller Bearings

This trackball uses roller bearings. That means, it can last long. Most other trackball use a fixed ceramic material that may wear out due to friction.

bar roller is used for heavier and larger trackball balls, so it's more smooth to roll, and contact does not wear down. Pictured is a older model. 5326×2996 〔image source geekhack
