Tamiya 15181 9mm Guide Roller Ball Bearings - Low Profile Upgrade  [15181]

Compact 9mm Guide Rollers for Mini 4WD Tamiya 15181

The Tamiya 15181 9mm Diameter Guide Roller Ball Bearings provide a precise, small-diameter option for Mini 4WD builders wanting tighter handling and consistent lap times. These are the smallest rollers in the Tamiya range and are useful for racers who need a lower profile setup while still allowing pairing with 13mm bearings for flexible tuning.

Engineered to lower friction and improve stability, these bearings help keep your Mini 4WD planted through chicanes and sharp corners. Their compact size contributes to a lower centre of gravity and makes them a good choice for technical track layouts where control and predictable response matter.
