This is an RC-scale ball bearing set intended for use with the TAMIYA M05 chassis and supplied under the 3Racing BS-M05PRO/V1 label. It is a replacement hop-up option designed to swap into common bearing locations on the M05 platform to maintain drivetrain rotation and reduce reliance on worn factory bushings.
The set is presented as a maintenance and tuning item rather than a performance miracle; installers will use it to restore smooth rotation in wheel hubs, transmission pivots, or other rotating points on the chassis that accept standard bearings. Because it is an accessory for model cars, compatibility is limited to M05-style bearing fits and related mounting points.
Installation notes: confirm bearing diameters and seat fits before pressing into place, use correct press tools or a soft-fit method to avoid cage damage, and follow normal RC-scale servicing practices such as cleaning old grease and reapplying a thin, appropriate lubricant if required by your setup.
