Jr-series 13mm Ringless Ball-Race Rollers Tamiya 92458 - Black Anodized  [92458]

Tamiya 92458 Jr 13mm Ringless Rollers in Black Anodized Aluminum

These 13mm ringless aluminum ball-race rollers are produced as a factory spare for Jr-series Mini 4WD applications. The part features a compact ball-race insert without an external retaining ring and a black anodized aluminum body. The reduced outer profile at the roller bore is intended for standard Jr chassis positions that call for 13mm rollers.

This is a themed regional anniversary release, so packaging and finish may differ from regular spares; collectors should note those cosmetic distinctions. For upkeep: clean the bearings with a proper solvent and use light lubrication; replacements should be fitted to compatible 13mm posts using existing Jr-series hardware where possible.

These rollers are designed as direct replacements or visual upgrades for Jr-series Mini 4WD models rather than as a broad performance part for other series.
