Tamiya 15522 HG 17mm Aluminum Ball Race Rollers - short summary

These Tamiya 15522 HG 17mm Aluminum Ball Race Rollers are built for hobbyists wanting a reliable, long lasting roller option. The aluminium construction and matte finish give a neat, race-ready look while remaining lightweight for agile handling.

Fitment, bearings and components

The rollers house a 520 ball bearing to ensure smooth spinning and consistent response when negotiating corners. The pack supplies two screws and four aluminium spacers for mounting on Mini 4WD and Mini 4WD PRO chassis. Be aware that some bodies require minor trimming for clearance.

Performance gains on club and home tracks

Installing these aluminium rollers can lower rotational friction and stabilise corner entry, helping maintain speed through technical sections. Their sturdy build is suited to regular track sessions and practise runs.

What tools do I need to install these rollers?

A small Phillips screwdriver, pliers for spacers and a hobby knife for any body trimming are usually sufficient. A set of metric hex drivers can help with finer adjustments.

Can I reuse bearings from older rollers?

If the old bearings are in good condition they can be reused, but 520 bearings in this kit are matched to the roller size for optimal performance.

How often should I inspect these rollers?

Check rollers after every few sessions for play, dirt build up and spacer alignment. Clean bearings and re-lube as needed to keep rotation smooth.

Will these affect top speed?

They are designed to reduce friction at the guide points, which can help maintain momentum through corners. Changes to top speed are minor and depend on overall setup.
