3RACING 3RB-MR105-ZZ/2 Precision Double Metal Shield Bearings 5 x 10 x 4 mm  [3RB-MR105-ZZ/2]

Performance Bearings for Tuning and Race Use

The 3RACING Double Metal Shield Bearing 5 x 10 x 4 mm is engineered for hobbyists focused on setup and lap consistency. These bearings deliver predictable rolling resistance, useful when dialling suspension and drivetrain balance.

Shielded for Reliability Under Load

Metal shields protect the raceways from grit while maintaining low drag characteristics, making them suited for higher RPM applications and controlled tuning environments. The standard 5 x 10 x 4 mm size integrates cleanly into common racing hubs and axle mounts.

Simple Upgrade for Consistent Outputs

Use the pair to replace worn bearings and restore symmetric wheel behaviour during cornering and acceleration. Their construction supports repeatable performance across practice and race sessions.
