3RACING 3RB-MR84-2RS/2 Double Rubber Sealed Bearings 4x8x3mm Spare Pair  [3RB-MR84-2RS/2]

Reliable sealed bearings for everyday RC use

Whether you are servicing a kit or refreshing worn parts, the 3RACING Double Rubber Seals Bearing in 4 x 8 x 3 mm size gives dependable rotation for common RC mounting points. Supplied as two bearings, the set suits hobbyists looking for straightforward, durable replacements.

Protection from dust and damp conditions

The double rubber seals act as a barrier against dirt, mud and light moisture. That protection reduces the need for frequent cleaning and helps the bearings maintain consistent feel and responsiveness during runs on varied surfaces.

Basic fitting and maintenance advice

Handle the bearings gently during installation and ensure housings are free of sharp burrs which can damage seals. Press evenly on the outer race and inspect regularly for noise or side play, replacing when performance drops.
