Tamiya 94861 JR 13mm Purple Ringless Rollers

The Tamiya 94861 JR 13mm Aluminum Ringless Ball Race Rollers are a practical parts upgrade for Mini 4WD builders. Removing the outer ring lowers contact drag on sidewalls, helping the car track cleaner through bends. Constructed from durable aluminum, these rollers are built for repeated use. The included 520 ball bearings provide reliable rotation whether fitted up front or at the rear. This purple release offers both performance and a vivid styling option.

Designed to work with Mini 4WD PRO and regular Mini 4WD models, these rollers slot into many common setups. They are a good pick when you need a low-friction roller that is simple to fit and maintain.

Will these suit high grip or low grip tracks?

They perform well across different surfaces. The ringless edges reduce snagging on track walls, which helps on high grip layouts, while bearings keep rotation consistent on smoother tracks.

Can I pair them with other rollers and spacers?

Yes. Mix and match with compatible rollers and spacers to tune clearance and balance. Check shaft length and spacer thickness before final assembly.

Do these add much weight to my car?

Aluminum rollers are slightly heavier than plastic, but the gain in durability and reduced friction often offsets the small weight increase for most setups.
