Precision Shielded Bearings for Tuning

For racers and tuners seeking consistent drivetrain behaviour, the 3RACING 3RB-MR126-ZZ/2 double metal shield bearings provide predictable low-friction rotation in a 6x12x4mm package. These bearings are intended to deliver repeatable spin characteristics that help maintain setup consistency between runs.

Metal Shielding for Controlled Contamination Resistance

Dual metal shields retard entry of abrasive particles while preserving bearing geometry and minimal running drag, making them suitable for competitive setups where service intervals are scheduled and predictable performance is required.

Compatibility and Fitment Considerations

The 6x12x4mm form factor aligns with common hub bores and axle shafts; ensure press-fit tolerances match your carriers for correct preload and alignment. These bearings are useful when optimising rolling resistance and rotational balance in competition vehicles.

What running clearance should I expect with these bearings?

Typical internal clearance is set to standard spec for 6x12x4mm shielded bearings; measure shaft and bore fits to verify preload and ensure smooth spin without axial play.

Which lubricant is recommended for race use?

Use a light, low-viscosity bearing oil for minimal drag in competition, and reapply at scheduled service intervals rather than heavy greases that increase rolling resistance.

Can I press these into aluminium carriers without modification?

Yes if the carrier bore matches manufacturer tolerances; check bore diameter and chamfer to avoid introducing stress or misalignment during installation.
