Ten 684ZZ miniature ball bearings for small motors and spinners

  • 10-piece set provides spare bearings for multiple builds
  • 684ZZ model fits standard 4 mm shaft applications
  • Carbon steel construction resists wear under load
  • Shielded design keeps dust out of the raceway

10-piece 684ZZ bearing set

This pack supplies ten 684ZZ miniature ball bearings built from carbon steel. They suit small motors, quadcopter rotors and fidget-spinner hubs that call for a 4 mm inner diameter, 9 mm outer diameter and 4 mm width.

Press-fit installation notes

The bearings are a press fit, so align them squarely before pressing to avoid binding or cage damage. A light oil film helps seating, but excess grit or sideways force will roughen the raceways and shorten service life.
