Protected Rolling for 3RACING 3RB-MR104-2RS_10

Built for practical use, the 3RACING Double Rubber Sealed Bearings 4x10x4mm (10 pcs) - 3RB-MR104-2RS_10 feature dual rubber seals that help keep contaminants out of the bearing interior. The 4x10x4mm size is common in many small RC assemblies and benefits from the extra sealing in gritty or damp conditions.

Practical Fitments and Uses

These sealed bearings are well suited to lightweight on-road cars and compact off-road rigs where space is tight but protection is needed. Their construction helps maintain smooth drivetrain and wheel operation even after repeated runs on rough surfaces.

Why Dual Seals Matter

Dual rubber seals reduce grease contamination and slow down ingress of water and dust, which lowers maintenance frequency and helps bearings run cleaner for longer in everyday hobby use.
