Smooth rolling with 3Racing 3RB-MR74-ZZ/2 bearings

Hobby drivers who want reliable componentry will appreciate the steady spin of the 3Racing 3RB-MR74-ZZ/2 double metal shield bearings. These 4x7x2.5mm bearings reduce internal friction and help maintain drivetrain efficiency across typical on-road and light off-road layouts.

Shielded faces for cleaner operation

Each bearing uses metal shields to help prevent dust ingress while allowing consistent rotation. The shields make these bearings a low-maintenance option compared with open types, saving time between servicing sessions.

Versatile spare for common fitments

With standard measurements, these bearings are suitable for many RC hubs and rotating assemblies. They are a sensible spare for regular maintenance kits and weekend track prep.

Do these bearings come as a matched set?

They are supplied as individual bearings; buyers typically fit pairs where required for wheel or shaft assemblies.

Will metal shields stop fine dust?

Shields reduce ingress of larger particles and grit, but very fine dust can still work its way in over time, so periodic checks are recommended.

Can I use these in my crawler or basher?

They suit many light off-road uses; for heavy rock crawling or deep water runs consider sealed or stainless options for extra protection.
