These hub - mountable aluminum gears are great for transferring motion from a motor or servo to a wheel or shaft. They have 76 teeth with a 32P gear pitch, an outer diameter of 2.488 inches, a 1 - inch bore, and use the 1.5 - inch hub pattern. Actobotics is a robotics building system featuring extruded aluminum channels, gears, precision shafts, and ball bearings. With two standardized hole patterns, most Actobotics components can be easily connected. The wide variety of components makes it possible to build complex electromechanical prototypes or finished projects. Dimensions: 76T at 32P teeth, 2.488” OD, 1” bore, 1.5” hub pattern.

Using these gears is easy. First, connect the gear to the motor or servo. Then, attach it to the wheel or shaft you want to move. This will let the motor's power transfer smoothly. When handling, be careful not to drop the gears as they might get damaged. Also, make sure the connections are tight. For maintenance, clean the gears regularly with a dry cloth to remove dust. Check the teeth for any signs of wear. If you notice any problems, replace the gear promptly to keep your project running well.
