The Tamiya 15180 - 13mm Guide Roller Ball Bearings are tailored for Mini 4WD racers seeking sharper cornering and steadier handling. Built to sit in guide roller positions, these bearings cut rolling resistance and help your car trace the line more reliably on tight bends.
This pack contains two ball bearings, each 13mm in diameter and 3mm thick, making them suitable for compact guide roller assemblies. Beyond lap speed, they deliver improved stability and control so builders can tune handling without compromising balance.
