Gearmotor Dimensions:

The face plate has six mounting holes evenly spaced around the outer edge threaded for M3 screws. These mounting holes form a regular hexagon and the centers of neighboring holes are 15.5 mm apart. You can use our custom-designed 37D metal gearmotor bracket to mount the gearmotor to your project via these mounting holes and the screws that come with the bracket.


Motor can be mounted with a bracket, sold separately.

Please note that unlike our smaller metal gearmotors, these 37D mm gearmotors have output shafts with a diameter of 6 mm. The hub in the picture can be used to mount custom wheels and mechanisms to the gearmotor’s output shaft.
