Performance Focused 3RACING 3RB-MR84-2RS/10 Bearings

Engineered for competitive hobbyists, the 3RACING Double Rubber Seals Bearing provides stable rotation and predictable friction characteristics. Supplied as ten 4x8x3mm units, they allow quick refreshes of wheel hubs and gearbox bearings to maintain consistent lap times.

Sealed Protection for Consistent Results

Dual rubber seals limit contamination and preserve internal lubrication, reducing variance in bearing behaviour during extended runs. This reliable sealing aids tuning accuracy when setting up a race car for tight, repeatable performance.

Application Notes for Tuners

These bearings suit wheel hubs, motor endbells and small gearbox outputs where a sealed 4x8x3mm bearing is required. Use them to reduce friction-related losses and to stabilise rotational elements in a race oriented setup.

What benefits do sealed bearings bring to a race car tuning session?

Sealed bearings reduce variability from dirt and lubricant loss, helping maintain consistent rotational friction between setups and runs.

Are these suitable for low friction axle applications?

Their sealed construction and standard dimensions make them appropriate for low drag axle and hub uses where the 4x8x3mm size is required.

How should a racer manage bearing replacements between events?

Keep spare bearings on hand, inspect for play or roughness during setup checks, and replace any units that show increased friction to preserve lap time consistency.
