Bosch Seat Motor 0.5 in. Hex Adapter Shaft

This shaft is an excellent solution for integrating the Bosch motor into a robot. There is only one problem I had. I suspect the dimensions for the shaft were specified without considering the plating thickness. I had to mill off part of the square shaft in order to get it to fit into the motor gear. I also had to shave the corners of the hex in order to get it to fit into the hex bearings. I appreciate that curvature was used at the transition from square to hex to avoid stress concentrations at that location. Generally a good design. It also comes with a washer and 6-32 screw to hold the shaft in place.

Well made and fits the final gear of the motor with a snug interference fit. Have not put it under load, yet.

Very good part to open up new low speed drive opportunities
