Tamiya 92458 Jr 13mm Ringless Aluminum Ball-Race Rollers (Black)  [92458]

Tamiya 92458 Jr 13mm Ringless Aluminum Ball-Race Rollers - Black Finish

These 13mm ringless aluminum ball-race rollers are supplied as a factory spare for Jr-series Mini 4WD models. The rollers use a compact ball-race cartridge without an outer retaining ring and a black anodized aluminum body. The ringless design reduces outer profile at the roller bore and is intended for standard Jr chassis mounting points where 13mm rollers are specified.

This release was issued as a themed regional anniversary item, so collectors should expect cosmetic and packaging variations compared with standard replacements. For maintenance: clean the bearings periodically with an appropriate solvent and apply a light lubricant; when replacing, use compatible 13mm posts and the original Jr-series roller hardware.

These parts are not promoted as a universal performance upgrade. They are intended as direct replacement rollers or aesthetic swaps for Jr-series Mini 4WD kits and for collectors who prefer the black anodized finish.
