Race-Oriented Sealed Bearings for Low Rolling Resistance

Precision bearings reduce parasitic losses in drive trains. The 3RACING Double Rubber Seals Bearing, 5 x 11 x 4 mm, supplied in a 10 piece set, is tailored for models where smooth, predictable rotation and minimal drag matter during laps.

Sealing That Preserves Race Consistency

Double rubber seals help keep contaminants out without sacrificing rotational speed, maintaining bearing integrity across multiple heats and practice sessions on dusty or damp tracks.

Broad Fit for Tuning and Setup Changes

The compact 5 x 11 x 4 mm size fits many hub, axle and gearbox locations used in competitive classes, making these bearings a practical choice when refining setup reliability.

Installation Notes for Optimal Track Performance

Install bearings concentric to their housings and verify minimal side load. Use a light, fast-penetrating oil for break-in and inspect seals between events to prevent performance drift.

Should I re-lubricate before a race day?

A quick light oil application at the seal edge can reduce initial friction; avoid heavy greases that slow small sealed bearings during competitive runs.

Do sealed bearings affect gearing feel?

Sealed bearings with correct lubrication offer consistent feel and predictable drag, which helps maintain consistent gearing response across laps.

Any tips for high RPM applications?

Ensure bearings are free of side loads and mounted true; for high RPM use, confirm seals rotate freely and consider low-viscosity oils for break-in.
