Race-oriented flanged bearings for precise installs

The 3Racing Double Metal Shield Flanged Bearing set in 4 x 7 x 2.5 mm delivers consistent rolling characteristics and protected lubrication for competitive setups. Supplied as a ten pack, these bearings are aimed at tuners who need repeatable, low-friction rotation in compact assemblies.

Performance Notes

  • Double Metal Shield: Keeps contaminants out while preserving internal grease to maintain low drag under race conditions.
  • Flanged Geometry: Ensures repeatable axial location and reduces setup variation when seating bearings in hubs and bulkheads.
  • Compact Dimensions: Fits tight arrangement points often found in high-precision layouts and tuned drivetrains.

How do these bearings affect lap consistency?

Reduced friction and stable seating help maintain predictable handling and consistent lap times, provided bearings are correctly mounted and lubricated.

Are they suitable for pinion and idler shafts?

They work well on low to moderate load pinion and idler shafts where a flanged locating face is required; verify shaft clearance and bearing load ratings for high torque setups.

How should I prepare bearings before a race meeting?

Clean externally, perform a light re-lubrication with race-appropriate oil, and inspect seating surfaces to ensure no play or misalignment before track sessions.
