This set includes two shielded ball bearings, precisely sized at 5mm inner diameter, 11mm outer diameter, and 4mm width. Constructed from high-quality steel with protective rubber shields, these bearings are designed to minimize friction and protect against dust and debris in the drivetrain. They are essential for ensuring smooth rotational performance in areas like wheel hubs, differentials, or gearbox shafts, contributing to reduced wear and improved efficiency of the RC vehicle's moving parts.
