Worm Motors

The NMRV worm gearbox is equipped with high-quality aluminum alloy casting and it adopts the advanced square box structure which is small in size, light in weight, and beautiful in appearance. The worm gear reducer could be matched with other gearboxes to reach a large ratio and torque. What’s more, due to the small size of the gearbox, it is easy to install and maintain. The NMRV worm gearboxes are manufactured with international technical requirements and possess a high technological content that guarantees high rigidity and high torque.
