3Racing 3RB-MR105-ZZ/10 Race-Oriented Bearing Upgrade

The 3Racing double metal shield bearings at 5 x 10 x 4 mm are supplied as a 10 piece set for routine replacement during race prep and setup changes. These bearings aim to minimise rotational drag and provide consistent feel across multiple service intervals.

Performance Advantages for Tuned Setups

Double metal shields reduce contamination ingress while keeping running resistance low, which helps preserve bearing geometry under load. Consistent rolling behaviour supports predictable steering and drivetrain response during tuning sessions.

Applications in Competitive Models

Intended for 1/10 scale race and club cars, these bearings work well in hubs, idlers and gearbox shafts where 5 x 10 x 4 mm bearings are specified. They are a practical maintenance item for teams and drivers who maintain a strict service schedule.

How do these compare to open bearings for lap time consistency?

Metal shielded bearings offer a balance between protection and low drag. They tend to deliver more consistent lap times in dusty environments compared with open bearings that foul quickly.

What checks are recommended during race day maintenance?

Inspect rotation smoothness, check for axial play and confirm shields are seated. Re-lube lightly if you detect increased friction between heats.

Should teams replace bearings between events?

Replace bearings based on performance checks. For competitive use, swapping bearings on a schedule prevents unpredictable failures during running.
