Low-Profile Ball Casters (2 Sets)

This set of two small, low-height ball casters is useful for those building any of Tamiya's educational robot model kits! They help create free movement on any robot with a low center of gravity. The metal ball with a diameter of about 1cm is fixed into a POM resin holder with four claws and low frictional resistance; then you can attach the holder part to a universal plate with one screw. It can be mounted flat, or set up with 5mm spacers and L-shaped parts to add some height. Modify your robot models for movement -- order yours today!
