Using this 90 Degree C - Type Hub Mount is easy. First, find the right position on your Actobotics channel where you want to attach the hub mount. Make sure the holes on the mount align with the holes on the channel. Then, you can use appropriate fasteners to secure it in place. You can attach shafts or tubes with a 0.5' diameter to the hub mount. When handling the hub mount, be careful not to damage the 0.5' bore or the hub pattern. For maintenance, keep it clean and dry. If it gets dirty, you can use a mild cleaner and a soft cloth to wipe it. Check the fasteners regularly to make sure they are tight. This will help ensure the long - term performance of the hub mount and your overall robotics project.
