RDF-NMRV Aluminum Worm Gearbox / Worm Gear Reducer with Output Flange
The RDF-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 RDF-NMRV worm gearboxes are manufactured with international technical requirements and possess a high technological content that guarantees high rigidity and high torque.

Advantages of RDF-NMRV Worm Gearbox | ||||
Low noise | This worm gearbox is smooth in transmission and is suitable for working in harsh environments for a long time. | |||
High efficiency | With the use of tin bronze worm gear material, this worm gear reducer is low in temperature-rising and fast in heat dissipation. | |||
High quality | The worm gear reducer is made of cast iron which is cast with an Aluminum mold. It`s good-looking and solid and can be used throughout the setting | |||
