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

Technical Upgrade: 3RACING 3RB-MR105-2RS/2 Sealed Bearings

For racers and tuners requiring consistent rotational behavior, the 3RACING Double Rubber Seals Bearings provide sealed 5 x 10 x 4 mm performance with reduced ingress risk. Supplied as a two piece set, these bearings are intended for precision fitments where stable shaft support and minimal maintenance are priorities.

Sealing and Durability Considerations

The double rubber sealing reduces contaminant entry while retaining factory lubrication, which helps preserve bearing smoothness under repeated track sessions. This construction extends usable service life compared with open bearings in dirty environments.

Installation and Application Notes

These bearings are suitable for small drive components, idlers and servo shafts where tight tolerances and consistent spin are required. Check housing bores and shaft runout during installation to ensure the bearing runs true and does not introduce binding into the drivetrain.
