The Tamiya 15180 - 13mm Guide Roller Ball Bearings are aimed at builders wanting tighter control and reduced drag at the guide points of their Mini 4WD. When fitted as guide rollers, these bearings help the car negotiate curves with less resistance and more predictable behaviour.
Contained in the kit are two ball bearings, each 13mm in diameter and 3mm thick, making them appropriate for many guide roller arrangements. By lowering friction, they support steadier corner speed and improved chassis balance during races.
