3RACING Double Rubber Sealed Bearings 5x11x4mm (10 pcs) - 3RB-MR115-2RS/10 Performance Set  [3RB-MR115-2RS/10]

Compact Bearings Designed for Consistent Rotation

Small bearings make a big difference to drivetrain efficiency. The 3RACING Double Rubber Seals Bearing in 5 x 11 x 4 mm form comes as a 10 piece set, ideal for replacing worn units in wheel hubs and pinion assemblies.

Extra Seal Protection for Dirty Tracks

Double rubber seals offer a barrier against dust and mud, helping internal raceways remain clear. That resilience reduces the need for frequent replacement when running on mixed surfaces.

Broad Compatibility with RC Hubs and Shafts

The standard 5 x 11 x 4 mm sizing makes these bearings suitable for a wide range of models and chassis layouts, enabling straightforward upgrades without special adapters.

Installation and Upkeep Tips

Press bearings in evenly and avoid tilting during fitment. Use a small amount of light oil on the seal edge if rotation feels stiff, and inspect seals periodically for nicks or wear.
