Tamiya 92458 Jr Lightweight 13mm Aluminum Rollers (Ringless, Black)  [92458]

Tamiya 92458 Jr 13mm Ringless Aluminum Ball-Race Roller Set (Black)

These ringless 13mm aluminum ball-race rollers are a factory spare intended for Jr-series Mini 4WD use. The design incorporates a compact ball-race cartridge with no external retaining ring and a black anodized aluminium body. The ringless format reduces bulk at the roller bore and suits standard Jr chassis mounting points that accept 13mm rollers.

This item was released as part of a regional anniversary edition, so finish and packaging may differ from standard parts; collectors should be aware of those cosmetic differences. Maintenance guidance: clean the bearings occasionally with a recommended solvent and apply a light lubricant; when swapping parts, use compatible 13mm posts and your existing Jr-series roller hardware.

These rollers are intended as direct replacements or aesthetic swaps for Jr-series Mini 4WD kits and are not a universal performance upgrade for other model ranges.
