In their manuals, Tamiya use references for their plastic and metal bearings: their ball bearings share the same reference. If most of the LHS know how to convert Tamiya references in standard measures, it's always better to check twice. Even more since Tamiya use the outer  / inner diameter convention to name their ball bearings when the industry uses the reverse. The following table will help: all measures are in millimeters.
