3RACING 3RB-MR84-2RS/10 Sealed Bearing Set 4x8x3mm 10 Pack  [3RB-MR84-2RS/10]

Fine Tune Performance with 3RACING 3RB-MR84-2RS/10

For model builders focused on sensible upgrades, the 3RACING Double Rubber Seals Bearing provides consistent, low friction rotation. Each 4x8x3mm bearing in this 10 pack supports smooth wheel and shaft movement while simplifying routine servicing.

Why Double Rubber Seals Matter

The twin rubber seals hold out grit and moisture so bearings keep rolling freely for longer. That makes them a good match for mixed surface running where wet grass or gravel can be a regular challenge.

Versatile Fit for Multiple Parts

These bearings are suitable for wheel hubs, gearbox outputs and small motor shafts across many models. Their common 4x8x3mm sizing and sealed construction make them a straightforward replacement part for model workshops.
