⚙️ Precision bearings for smooth, efficient performance.
Keep your drivetrain rolling at peak efficiency with Traxxas 10x15x4mm Ball Bearings. Available in two versions — black-sealed and blue-sealed — both deliver the precision fit and durability you expect from genuine Traxxas parts, with slight differences in seal type and intended usage.
🔹 Blue-Sealed [5119]

Ideal for off-road or wet-condition running
-
Slightly more seal drag, but greater protection in harsh environments
⚫ Black-Sealed [5119A]
-
Tighter seal for reduced debris ingress, but optimized for lower rolling resistance
-
Suitable for high-speed on-road or clean-condition running
-
Minimal seal friction for smoother free-spinning performance
