Sturdy Roller Fixings with Tamiya 94699 - HG Threaded Bearing Bushing

The Tamiya 94699 HG Threaded Bearing Bushing is a practical upgrade for Mini 4WD models where stronger roller fixing is required. The set includes four threaded bushings and a handy wrench, engineered for use with 9mm, 10mm, 11mm and 13mm guide roller ball bearings. The threaded assembly improves the strength of the screw joint, reducing bending and helping the roller retain its angle even after heavy impacts.

These bushings are finished in nickel-plated brass for resilience and a neat appearance on the car. They are intended to remain firm even if a securing nut loosens during running. Ball bearings are not part of the set; compatible Tamiya bearings include DR 9mm Ball Bearings (Item 15344), DR 11mm Ball Bearings (Item 15345) and Mini 4WD 13mm Dia. Guide Roller Ball Bearings (Item 15180).

Will these improve cornering stability?

By keeping roller alignment and reducing screw flex, the bushings help maintain consistent roller angles, which can contribute to steadier cornering behaviour on the track.

Are the bushings compatible with plastic rollers?

Yes, they work with many plastic or metal rollers provided the roller uses one of the supported bearing sizes. Check the roller inner diameter to confirm fit.

Can these be used as a permanent upgrade?

They are durable and intended for long term use, but regular checks of tightness and condition are recommended after competitive runs.

What should I check after fitting?

Verify that the bushings are seated correctly, the roller spins freely with the chosen bearing, and that all screws are tightened to a safe level without over-torquing.

Do these replace the need for lock nuts?

They improve retention compared to plain spacers but do not necessarily remove the benefit of using lock nuts or thread-lock solutions in high-vibration setups.
