3Racing 3RB-MR74-ZZ/10 4x7x2.5mm Double Metal Shield Bearings - Spare Kit  [3RB-MR74-ZZ/10]

Robust 3Racing metal shield bearings for steady rotation

Hobbyists seeking reliable running will value the 3Racing 4x7x2.5mm Double Metal Shield Bearings for their low friction and consistent manufacture. These bearings support cleaner drivetrain feel and reduced mechanical noise when installed correctly.

Shielded design advantages

Double metal shields help shield the internals from dust while allowing the race to spin freely, extending service intervals and reducing the chance of premature failure in typical onroad and light offroad use.

Applications and fitment notes

The 4x7x2.5mm size is common in small hubs, motor mounts, and steering components, so these bearings are a sensible addition to your spares box for maintenance and quick fixes.
