Performance Focused Sealed Bearings

The 3Racing Double Rubber Seals Bearing (3/16 x 3/8 x 1/8) is intended as a direct service item for racers needing sealed rolling elements to preserve lubricant and limit debris ingress. These bearings help sustain consistent rotational characteristics across practice and race sessions.

Sealing and Longevity Considerations

Double rubber seals reduce contamination risk and help maintain bearing lubrication under repeated use. For tuning and setup changes, sealed bearings can reduce the need for frequent cleaning and allow more predictable drivetrain behaviour.

Technical Highlights

  • Double rubber seals for improved defence against dust and grit
  • Compatibility with common hobby RC bearing locations using the same dimensions
  • Designed to reduce rolling resistance for steadier drivetrain response

Will sealed bearings affect top end speed or acceleration?

Sealed bearings typically run with reduced contamination and stable lubrication, which can help maintain repeatable acceleration and top speed compared with older, contaminated bearings.

Are these bearings intended for tuning upgrades?

They are suitable as a maintenance or upgrade item where sealed operation is preferred to reduce downtime and preserve drivetrain consistency during tuning cycles.

How should these be inspected between race runs?

Check for smooth rotation, any side play, and seal condition. Replace if roughness or play appears to avoid transmitting wear to other drivetrain components.
