This 42-piece metal shielded bearing pack fits the Tamiya 56366 Mercedes-Benz Arocs 4151 and gives a straightforward way to reduce rolling resistance. It is aimed at hobbyists who want dependable, low-maintenance bearings for regular use.
Metal shields provide lower friction than many sealed rubber options, helping the truck run more freely and use battery energy more efficiently. The shields also offer basic protection from dust and grit so bearings keep performing between services.
