3RACING Double Rubber Seals Bearings 5x10x4mm (2 pcs) - 3RB-MR105-2RS/2 - Hobbyist Sealed Bearings  [3RB-MR105-2RS/2]

Improve Rotation Consistency with 3RACING 3RB-MR105-2RS/2

Swap in the 3RACING Double Rubber Seals Bearings to reduce play and improve shaft spin in small RC assemblies. These 5 x 10 x 4 mm bearings arrive as a two piece set and are suited to common maintenance and small upgrades. They help restore smooth operation where older bearings have started to bind or rattle.

Protection from Dust and Moisture

The double rubber seals act as a barrier against fine dirt and light moisture, helping the internal race stay clean and the bearing retain consistent performance over longer intervals between services.

Where to Use These Bearings

Use these bearings across a range of small RC components such as idler shafts, servo linkages and gearboxes. They are a practical upgrade for hobbyists seeking reliable sealed performance without specialised tools.
