The Kyosho BRG405 bearings are a set of four shielded 4x8x3mm bearings intended to improve rotational smoothness in small RC assemblies. They are a compact, serviceable option when replacing worn bearings in wheels or gearboxes.
The shielded design helps limit ingress of dust and debris while keeping rolling friction low, which can lengthen the service life of associated parts. Their small size allows them to be fitted into a variety of confined locations on scale vehicles.
These 4x8x3mm bearings are compatible with many model types that specify the same dimensions, making them a sensible spare for workshop maintenance or on-event repairs. Stock a set to speed up routine swaps.
