If you need dependable small bearings for everyday RC maintenance, the 3RACING Double Metal Shield Bearing 4x8x3mm pack gives a straightforward upgrade. These bearings are built to reduce friction and help keep moving parts spinning freely under typical hobby loads.
The 4x8x3mm size works in many hubs, axles and gearbox points on 1/18 to 1/10 sized models. These compact ball bearings lower rolling resistance and improve drivetrain efficiency on both paved tracks and rougher surfaces.
The double metal shields block most dust and grit while allowing smooth rotation, which helps extend service intervals. For models used in dusty conditions, these shields add useful protection compared with open bearings.
These bearings are a versatile spare for racers and casual drivers alike, fitting a wide range of kits and upgrades. Keep a set on hand for routine repair jobs or when swapping wheels and axles.
