Race-Oriented Flanged Bearings for Tight Tolerance Use

Built for setups where consistent rotation matters, the 3Racing 3RB-MF63-ZZ/2 flanged metal shield bearings in 3x6x2.5mm format deliver guarded rolling surfaces and predictable spin characteristics. The flange assists repeatable seating in hubs and carriers while the metal shields reduce ingress that can destabilise bearing behaviour during intense running.

How should I verify these for my race chassis?

Check bore diameter and flange thickness against the chassis drawings, and confirm axial location to ensure the flange provides correct lateral support without binding.

Do metal shields affect running freedom compared to open bearings?

Shields add protection with minimal impact on low speed drag; for ultimate free spin open bearings may be used on spares, but shields give better longevity under dirty track conditions.

Any installation tips to preserve bearing alignment?

Use a straight press or a socket sized to the flange to avoid loading the inner race. Inspect seating after the first few runs and recheck for play as part of race prep.
