Performance Bearings for Competitive Setups

Engineered as a matched pair, the 3RACING Double Metal Shield Bearing 8x12x3.5mm is intended for racers who want stable, predictable rotation in drivetrain and wheel applications. The shields limit debris ingress while maintaining consistent running characteristics under load.

Shielding That Supports Tuning

Metal shields offer robust protection without significantly increasing drag, which helps maintain lap-to-lap consistency. These bearings suit fine-tuning routines where bearing condition affects steering precision and corner speed.

Application and Upgrade Notes

Designed to interchange with standard 8x12x3.5mm locations, these bearings are a cost-effective upgrade for improving drivetrain smoothness. Replace bearings in matched pairs and evaluate lubrication choices to match your race conditions and setup preferences.

Which positions benefit most from these bearings?

Wheel hubs, idler pulleys and diff locations that accept 8x12x3.5mm bearings see the greatest handling gains from reduced friction and consistent rotation.

What lubrication strategy works for racing?

Use a light, long-lasting bearing oil that preserves shield performance while minimising drag; heavier greases are better for longevity but can affect top-end responsiveness.

How should I inspect bearings between events?

Rotate each bearing by hand to check for smoothness and listen for roughness; replace any with noise or play and keep spares for quick swaps during events.
