Bearing Specification Overview

These 3RACING Double Metal Shield Bearings 5x9x3mm provide sealed protection and predictable running behavior for performance-oriented models. The double-shield construction helps retain lubrication and limits ingress of abrasive particles during racing or tuning sessions.

Shielding and Construction

The dual metal shields offer robust defence against contamination while maintaining internal clearance for stable low-friction operation. This construction supports consistent lap times and reduces variation due to dirt ingress in moderately dirty environments.

Application and Fitment

At 5x9x3mm the bearings are compatible with many small RC applications including wheel hubs and idler shafts; correct seating and axial alignment are key to maximising service life. Regular inspection and scheduled relubrication will help sustain bearing performance under competitive use.

What precautions should I take when installing these bearings?

Press bearings straight into the housing using a driver that contacts only the outer race, and verify there is no axial preload that could increase friction or wear.

How do I inspect these bearings for race readiness?

Spin each bearing by hand to check for smoothness and listen for roughness; check for lateral play and ensure shields are seated evenly before track use.

What maintenance keeps them race-ready?

Schedule routine checks, remove contaminant buildup around housings, and reapply a light high-quality lubricant as needed to maintain low friction under high RPMs.

Are these bearings suited to tuning upgrades?

Yes, their sealed design and consistent rotation make them a sensible upgrade when tuning drivetrain efficiency or reducing drag in competitive setups.
