We have designed this mount for mounting NEMA 34 steppermotors to many of our retrofit kits. Its used in the kit for the BF30 and BF46 but also in the kit for our lathe D240x500. Since we make it in such big numbers, we can offer it for a goodprice. The product is of high quality, CNC milled and then grey anodized. It will fit any industry standard NEMA 34 steppermotor/servo. Do take into account that you need 2 mounts per motor.
