These flanged ball bearings fit nicely into an 8mm diameter hole and has a 3mm bore. This makes it perfect for all Actobotics channels, hub mounts, or any 8mm hole where you need to run a 3mm shaft. Each order is sold in packs of two.

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.
