4 Pcs 37mm Diameter DC Gear Motors Mounting Bracket Black Rust Resistance Gearbox Fixed Seat Gear Reduction Motor Holder with 4 Pcs 6mm Hex Coupling for Small Stepper Motors

They work as advised. The mounting holes intended to secure to the chassis that we used it on were small and made it difficult to attach to the chassis. Could not drill out the mounting holes to even fit wood screws in (we had a wood chassis)

The hole pattern matches my gear motor very well, I found the metric allen head(socket head cap screws) at a fastener supply,,tossed the brass stuff and mini lathed 1/2" coupling instead

The bracket, the part I needed the most works just fine. The couplers were a bonus but don't work for me. I need a 6 to 7mm and this came with 6 to 4 coupler. I was also disappointed that there were no mounting screws for the bracket, just the the coupler plugs.The kit is OK. If you have the screws for the motor already and the coupler will suit your needs, it might be a win.

Fit my motors just fine. Minimal flexing..

Arrived on time and in good condition. Good value.

Quality all the way.

Good product
