Re: Method to direct drive HEX Shaft

These motors use sleeve bearings at both ends of the shaft. Excessive side forces on the shaft can and will damage one or the other. One of our team mates broke the bearings at the back end of a CIM that was direct driving a Frisbee shooter wheel when he used too much compression. It only took about 3 shots to damage it.

Kevin's suggestion to use the 1:1 Versa Planetary is the best of the solutions presented because the shaft in the VP has it's own bearings and they absorb the side forces and don't transmit them on to motor shaft.
