For racers refining drivetrain response, the 3RACING flanged bearings provide predictable rolling characteristics. Their shielded construction and flanged seating make them suitable for tuning and reliable track use.
The double metal shields reduce contamination while the flange offers repeatable axial location in hubs and carriers. That combination helps maintain stable running characteristics under varied track conditions.
The 3x6x2.5mm size is common in many competitive small-scale assemblies. Verify housing thickness and flange clearance when fitting to maintain accurate alignment and minimal drag.
