These Kyosho BRG414 bearings measure 10 x 15 x 4 mm and are supplied as a set of two for 1/10-scale RC applications. They provide the rolling interface for wheel hubs, gearbox shafts and other confined drivetrain positions that require a shielded bearing. The shields help keep grit out while permitting smooth rolling under normal hobby loads.
Fitting notes: press the bearing in squarely using even force and avoid striking races directly to prevent brinelling. During routine checks swap bearings that show play, rough feel or audible noise to maintain reliable drivetrain performance.
A practical replacement bearing set for standard 1/10-scale drivetrain servicing and light tuning where a compact shielded bearing is required.
