The AmpFlow Wheel/Gearmotor combinations can be configured with your choice of six different wheel sizes, several different motors, and various different reduction ratios. This page shows the 27:1 ratio option.
The high-traction solid rubber wheels are 1.5 inches wide, and they range in diameter from 4 inches to 10 inches. The big pneumatic 12.5-inch wheel pictured on the left is 2.75 inches wide.
The wheels have a custom hub that is keyed to the 3/4-inch shaft of the speed reducer. The wheel is assembled with 1/4-inch keys and held in place by two steel discs and a spacer. The whole assembly is held together by a 5/16-18 screw that threads directly into the shaft.
This combination of high power, high traction, and light weight make these wheels ideal for robots and other mobile applications.
