Buying tips

When choosing RC engine bearings, consider the environment (e.g., off-road vs. on-road), RPM requirements, and budget. Rubber-sealed bearings (RS) are best for dusty conditions, while metal shields (ZZ) allow lower friction but less protection. Ceramic hybrids offer the highest performance but cost more. Always match the size (inner/outer diameter and width) to your specific model.
