Manufacturers of machinery for the US market are well aware of the need for NEMA standards, which are different from the metric standards in use on the majority of markets. We make NEMA worm gearboxes especially to satisfy these requirements, both for US manufactures and for any other company whose machines and systems are sold on the US or Mexican marketplace. From a performance viewpoint, the NEMA gearboxes are the same as those of the CM series.
