The Yokomo BB-63-2A 3x6x2.5mm ball bearings deliver precise rolling performance for small RC applications. They feature a 3mm bore, 6mm outside diameter and 2.5mm thickness, matching common fitments on many compact chassis points.
These bearings are compatible with Yokomo chassis such as DP-DIB2 and MRTC-BD8 variants. They work well as replacements for worn units or as part of a tune-up for racers seeking lowered friction and consistent behaviour under load.
