Description: These ball bearing hubs from Actobotics are great when you need to securely fasten a free-spinning shaft to a stationary channel to drive a pulley, wheel, or other rotating device. Each ball bearing hub has an outer diameter of 1", a bearing bore of 0.25", a thickness of 0.5", and utilizes the 0.77" hub pattern.

Actobotics is a robotics building system based around extruded aluminum channels, gears, precision shafts, and ball bearings. Thanks to the two standardized hole patterns, nearly all Actobotics components can be intuitively connected together. The wide range of components makes building complex electromechanical prototypes or finished projects a reality.

Dimensions:

  • OD - 1"
  • Bearing Bore - 0.25"
  • Thickness - 0.5"
  • Hub Pattern - 0.77"

  • I have a 4 mm diameter motor shaft. Will this fit onto the shaft?

    • NO. The ¼" bearing bore is 6.35mm, so the 4mm shaft would just be floating in the bearing hole.

      I was looking for a 5mm and 6mm bearing bore size, but they do not seem to do the metric sizing and have a very limited range of bearing bore sizes.
