Race-focused sealed bearing solution

The 3Racing Double Rubber Seals Bearings, 3/8 x 5/8 x 5/32 inches, are specified to reduce rolling resistance while maintaining a sealed environment around the raceways. These bearings are intended for wheel assemblies and drivetrain locations where consistent spin and protection from track debris are important for lap time stability.

Sealing and longevity for tuning consistency

Double rubber seals help preserve internal lubrication and prevent abrasive particles from degrading the races. For racers this translates to more predictable bearing behavior between service intervals and fewer mid-event changes.

Fitment and setup considerations

These bearings suit a range of common racing chassis layouts and can be used as an efficient upgrade to lower rolling drag without major suspension alterations. Carry spares from the 10 piece pack to support setup tuning and reduce pit downtime.

Should I change lubricant for racing use?

Sealed bearings are supplied with factory lubrication; if a different lubricant is preferred for specific track conditions, consider replacing rather than attempting complex resealing.

How do these bearings affect handling at high speed?

Lower rolling resistance can improve top-end speed and reduce drivetrain losses, which helps maintain consistent handling during long runs when other elements are equal.

What tolerance checks should I perform when fitting?

Verify shaft and bore dimensions for a light, even press fit and check for smooth rotation without radial play after installation to avoid premature wear.

How many spares should a race team carry?

Keep a set of spare bearings per wheel plus extras for differential and gearbox locations; the 10 piece pack provides a practical buffer for typical event needs.
