The construction utilizes high-grade steel races to ensure structural integrity and consistent rotational performance under load.

Key Features

• Dimensions: 15x21x4mm fitment for specific Team Associated chassis models.
• Sealed Design: Equipped with vibrant blue rubber seals on both sides to prevent dust, dirt, and moisture ingress.
• Material: Polished steel races provide smooth operation and resistance to wear during high-speed runs.

Application & Maintenance

These sealed bearings are intended for use in the drivetrain, steering, or suspension assemblies of compatible RC cars. The rubber lip seals offer protection against debris accumulation, which helps maintain efficiency and extends service intervals compared to open bearings. Install these units when original bearings show signs of roughness, noise, or play to restore optimal handling characteristics.
