Upgrade Bearings for Smoother Running with 3RACING 3RB-MR105-2RS/2

If you want a straightforward way to reduce friction and stabilise wheel or drivetrain rotation, the 3RACING Double Rubber Seals Bearings are a solid choice. These 5 x 10 x 4 mm sealed bearings come as a pair and are built to deliver steady, low-resistance operation for everyday use. Two bearings per pack make them handy for quick replacements or routine servicing.

Why Rubber Seals Matter for Longevity

The double rubber seals keep grit and moisture out of the race, helping the bearing retain smooth spin for longer. That protection is especially useful when running on dusty tracks or damp surfaces where unsealed bearings tend to ingest contaminants.

Common Uses and Fitment Notes

These bearings suit many small RC applications from steering assemblies to gear shafts. They work well for hobbyists replacing worn parts or fitting a simple sealed upgrade to extend service intervals and improve reliability.
