Advantages of NRV-E Worm Gearbox

  • Low noise

The PC-NMRV worm gearbox is smooth in transmission which is suitable for working in harsh environment for a long time.

  • High efficiency

With the using of tin bronze worm gear material, the Taiqi PC-NMRV worm gearbox is low in temperature-rising and fast in heat dissipation.

  • High quality

The reducer made of cast iron which casted with Aluminum mould. It`s good looking and solid, and can be used through the setting of multi-azimuth.


The NRV-E worm gearboxes are widely used in automation industry, industrial robots, aerospace, CNC machine tools, metallurgical mining, beer and beverage, tobacco light industry, environmental engineering, warehousing logistics, plastics machinery, lifting transport, three-dimensional parking, automobile manufacturing, textiles, food, ceramics and other fields.
