Technical Upgrade for Competitive RC

The 3Racing Double Metal Shield Bearings (8x14x4mm) are specified to reduce rolling resistance and deliver repeatable rotational performance for hubs, shafts and transmission components in race setups. Their shielded construction balances protection with minimal added drag.

Shield Design and Service Life

Dual metal shields protect the raceways from particulate ingress while maintaining close running clearances. This design aids longevity under dusty track conditions and reduces the frequency of bearing-related service interventions.

Application and Fitment

As a standard 8x14x4mm unit, these bearings integrate into common chassis locations across touring, buggy and on-road race cars. They are suitable for teams looking for durable, easy-to-service bearing options that do not require extensive modification.

What tolerances should I expect from these bearings?

These bearings meet common hobby-grade tolerances suitable for normal competition use; they provide consistent axial and radial clearance for predictable handling.

Are they suitable for high speed spool or motor mount applications?

They perform well at typical hobby motor and spool speeds, but verify load and rpm against your specific drivetrain to ensure optimal life.

Recommended maintenance practices for race use?

Inspect bearings between meetings, clean shield faces and relube with light bearing oil where permitted; replace bearings showing play to maintain consistent lap times.
