3RACING Double Rubber Sealed Bearings 3 x 6 x 2.5 mm (2 pcs) - 3RB-MR63-2RS/2  [3RB-MR63-2RS/2]

Performance-Focused Sealed Bearings for Race Use

The 3RACING 3x6x2.5mm double rubber sealed bearings deliver consistent rotational performance while guarding the raceways from debris. Their sealed construction reduces friction variability, which helps preserve predictable drivetrain behaviour under race loads.

Seal Integrity and Rolling Consistency

Dual rubber seals maintain contaminant exclusion without compromising internal lubrication. This stabilises bearing drag and supports repeatable lap times by lowering the chance of mid-session performance shifts caused by ingress.

Compatibility and Service Considerations

These bearings drop into most 1/10 scale hubs designed for 3x6x2.5mm units and are intended as low-service alternatives to open bearings. For competitive use, inspect fitting tolerances and ensure proper preload to avoid axial play that could affect handling precision.
