For racers and tuners seeking predictable spin characteristics, the 3RACING Double Metal Shield Bearing 10x15x4mm provides consistent rolling resistance and reliable service intervals. The pair is suited to locations where repeatable bearing behavior supports setup tuning.
The double metal shields reduce the ingress of abrasive particles and help preserve internal lubrication, which aids stable performance across multiple runs and reduces the frequency of bearing swaps during race weekends.
Use these 10x15x4mm bearings in positions where minimal play and steady rotation influence handling and power delivery. They are convenient for quick refreshes during pre-race checks or as part of a measured upgrade strategy.
