Tamiya 94768 Jr Bearing Roller Spacer - 20pcs set

The Tamiya 94768 Jr Bearing Roller Spacer set contains 20 spacers for adjusting roller spacing on Mini 4WD cars. This kit helps modellers achieve repeatable setups for different race conditions.

Which rollers work with these spacers

These spacers are compatible with a variety of Tamiya Mini 4WD roller types and are commonly used with 19mm and 17mm aluminium ball-race rollers. They provide the flexibility to fine tune alignment and reduce lateral play in the roller assemblies.

Why spacer choice matters on track

Adjusting spacer thickness affects how the car negotiates corners and how firmly rollers contact guards. Using the Tamiya Jr Bearing Roller Spacers lets racers balance cornering confidence and straight-line speed without changing core parts.
