3RACING 3RB-MR63-2RS/10 Double Rubber Sealed Bearings 3x6x2.5mm (10 pcs)  [3RB-MR63-2RS/10]

Race-focused sealed bearings for tuning

Designed with competitive use in mind, the 3RACING Double Rubber Seals Bearing offers a sealed option that helps preserve bearing life under race conditions. At 3x6x2.5mm, these bearings are sized for small shafts used in steering assemblies, hubs, and lightweight gear trains.

Durability under track conditions

The double rubber seals provide a robust barrier against dust and particles that can degrade bearing performance. For racers who frequently swap components between sessions, sealed bearings reduce downtime and the need for frequent cleaning.

Consistent rolling for setup tuning

These bearings maintain steady rolling resistance that aids predictable drivetrain behavior when testing spring, gear, and tyre changes. Their compact size makes them a useful option for fine-tuning small rotating assemblies without significant modification.
