The 3Racing M18T-28 is presented as a full ball bearing replacement set intended for the XRAY M18T 1/18-scale RC chassis. As a scale accessory, its purpose is to replace worn bearings in the drivetrain and wheel hubs, restoring rolling smoothness and reducing friction in moving assemblies.
Installation is typically straightforward for hobbyists familiar with small-scale maintenance: remove the old bearings from hubs, diff cases, and gear carriers, clean mating bores, and press the new bearings in squarely. Use a bearing press or a suitably sized driver to avoid applying force to the inner race. After fitment, rotate assemblies by hand to confirm free movement before reassembly.
For tuning and maintenance, a full bearing set simplifies routine servicing and pre-race checks. Regular inspection for play, noise, or rust helps determine when replacements are needed. Light bearing grease or dedicated bearing oil can be used as part of a maintenance routine, but follow the lubricant recommendations for your specific drivetrain components to avoid contamination of gear teeth or clutch systems.
