Tamiya 92458 Mini 4WD Jr 13mm Black Ringless Ball-Race Rollers  [92458]

Tamiya 92458 Mini 4WD Jr 13mm Ringless Ball-Race Rollers - Black

These 13mm ringless aluminum ball-race rollers are an official spare part for Jr-series Mini 4WD applications. The rollers incorporate a compact ball-race insert without an outer retaining ring and carry a black anodized aluminium finish. The ringless arrangement trims the external profile at the roller bore and is intended for standard Jr chassis locations where 13mm rollers are specified.

This set was released as a themed regional anniversary edition, so collectors should note the distinct finish and packaging compared with standard replacements. For upkeep: clean the bearings with a suitable solvent and apply light lubrication; replacement should use compatible 13mm posts and the existing roller hardware from Jr-series setups.

These rollers are supplied as direct replacements or cosmetic swaps for Jr-series Mini 4WD kits rather than as a general performance upgrade for other model series.
