Performance Notes for Tamiya 94956 JR 19mm Aluminum Ball-Race Roller

The Tamiya 94956 JR 19mm Aluminum Ball-Race Roller in striking orange adds a low-mass, durable rolling element to Mini 4WD machines. With 520-size bearings installed, these rollers offer smoother rotation and lower rolling resistance compared with plain bushings, which can help with lap time consistency.

Rubber rings around the roller surface reduce contact damage when brushing the track sidewalls, protecting both the roller and the car's bodywork. The colour also helps with quick visual checks during practice sessions and makes it easier to spot wear or alignment issues before a race.

Can I replace my current rollers with these 19mm units?

If your car accepts JR 19mm rollers, these will slot in as a direct upgrade. Confirm axle length and mounting position to avoid clearance problems with wider bodies.

Do the rubber rings affect grip or handling?

The rubber rings primarily protect from impact and reduce scraping noise. They have minimal effect on grip compared to tyre and suspension setups, but they do help maintain stable contact with guide rails.
