The Yokomo YOKBB105T2 product is a set of two 5x10x3mm metal ball bearings meant for micro and small-scale RC driveline roles. These bearings are tailored to compact shaft diameters and tight assembly spaces within small electric models.
They function to support rotating shafts, lower friction, and help preserve correct tracking of gearbox and wheel components under load. Common fitting locations include tiny motor shafts, pinion/spur bearing seats, and compact differential or hub bores where a 5x10x3mm bearing is appropriate.
Installation typically involves pressing or seating the bearing into the bore, verifying axial alignment, and retaining with the model's original clip or screw where required. Replacing worn bearings with low-tolerance, clean units can noticeably reduce drivetrain drag and improve smoothness under throttle changes.
Packing: 2 pcs per pack as supplied by the manufacturer.
