These cylindrical brushed DC gearmotors are available in a wide range of gear ratios, from 25:1 up to 488:1, and with three different motors: 6 V and 12 V motors with long-life carbon brushes (CB), and a 6 V motor with shorter-life...

These versatile wheels use interchangeable collets to tightly grab a variety of different common motor shafts, including the 3mm D-shafts on our micro metal gearmotors and mini plastic gearmotors and the 4mm D-shafts on our 20D metal...

"You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them...

This ball caster kit includes a black ABS housing, a 3/4″ diameter plastic ball, three dowel pin rollers, two spacers (1/16″ and 1/8″ thick), and two 7/16″ #2 screws and nuts. The total height of the ball caster, 0.88″, can be increased...

These wheels are great for robotics, custom RC vehicles, or any other project you need to get rolling. They measure 40 mm (1.57″) in diameter and are designed to press-fit securely onto D output shafts with a diameter of 3 mm. They are...
