Tamiya 15522 HG 17mm Aluminum Ball Race Rollers - Ringless Performance Rollers for Mini 4WD  [15522]

Overview - Tamiya 15522 HG 17mm Aluminum Ball Race Rollers

The Tamiya 15522 HG 17mm Aluminum Ball Race Rollers are aimed at racers seeking a reliable, well made roller option for tighter tracks. Constructed from aluminium with a subdued matte finish, they are made to blend function with a clean aesthetic.

Compatibility, bearings and included parts

These rollers use a 520 ball bearing to ensure smooth rotation and steady handling through corners. The package includes two screws and four aluminium spacers to fit Mini 4WD and Mini 4WD PRO chassis. Note that some car bodies may need slight trimming to provide adequate clearance.

Benefits during racing and upkeep

Fitting aluminium ball race rollers can reduce friction at contact points and help provide more predictable cornering behaviour. Their durable build is suited to regular race use provided bearings are kept clean and lightly lubricated.
