Technical overview of 3Racing sealed metal bearings

These 3Racing 5x13x4mm Rubber Sealed Metal Bearings are produced to provide repeatable rotational performance in demanding RC applications. The sealed assembly preserves internal lubrication and reduces contamination-related wear on the raceways and balls.

Engineering and performance notes

  • Durability: Metal shields combined with dual rubber sealing create a barrier against abrasive particles and moisture, improving fatigue life under intermittent exposure.
  • Dimensional use: At 5x13x4mm, the bearings fit common small-diameter shafts used in gearboxes, wheel hubs and idler positions where tight tolerances are required.
  • Operational efficiency: Precision ground races and consistent internal clearance lower rolling resistance, aiding temperature control and consistent lap-to-lap performance.

What clearance class do these sealed bearings use?

Factory sealed bearings are supplied with a standard internal clearance suitable for general RC use; for precision setups, check fitment and consider shim or preload adjustments to control endplay.

How should I integrate them into high RPM drives?

Ensure correct shaft concentricity and secure retention to avoid eccentric loading. Proper lubrication and sealed protection will reduce the risk of overheating at sustained high RPM.

Are these bearings suitable for precision tuning work?

Yes, they are useful for tuning where sealed, consistent bearings reduce variables in drivetrain behaviour; pair with precision mounts and regular inspection for best results.
