Precision Shielded Bearings for Tuned Setups

The 3RACING Double Metal Shield Bearing 3 x 8 x 3 mm is specified for applications where repeatable rotational performance matters. These bearings help reduce parasitic friction in wheel and gearbox assemblies while providing shielding against track debris.

Racing-Focused Shield Benefits

The double metal shield format improves resistance to particulate ingress without adding significant drag, making these bearings well suited to practice and club racing environments. They balance protection with low rotational resistance for predictable handling.

Installation and Tuning Notes

Install these bearings in housings designed for 3 x 8 x 3 mm bearings, checking for correct seat and minimal lateral play. Use a light bearing lubricant to achieve a compromise between top-end speed and dependable load carrying during race runs.

Can these bearings handle high track RPMs?

Yes, within hobby racing RPM ranges these shielded bearings perform reliably; for extreme RPM applications consider specialist high speed bearings with tighter tolerances.

How do I check for proper bearing fit?

Ensure the inner race slides onto the shaft with minimal play and the outer race seats squarely in the hub. Any wobble indicates misfit or housing wear that should be addressed.

What maintenance keeps them race ready?

Regular inspections, light lubrication and cleaning after dusty or gritty sessions maintain low friction and consistent performance between events.
