Description: Quad block bearing mounts attach to the inside of a channel and have a ball bearing with a 1/2” bore for shafts. These bearing mounts have a width of 1.32”, a thickness of 0.25”, a 0.50” bore bearing, and utilize 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.

Customer Comments

  • Having just one of these in stock is not very useful. Do you plan to get more in stock?

    • As it is not a huge seller our system doesn’t tell us to reorder until we are out of stock. Feel free to place an order for the number you need and once the backorder is in the system we should order more. I’ll see about getting more in though.
