RV Series NMRV 075 Gearbox Advantages

The RV series NMRV 075 gearbox is an advanced version of the classic worm gear motor. It offers precision ball bearings, synthetic lubrication, and die-cast aluminum near-net tooling. Its unique design is generations ahead of older cast iron worm gears. It is ideal for both small and large worm gearing, ensuring smooth operation.

The worm gear and pinion are made of 10-1 tin bronze to ensure optimum casting properties. The worm is made of 20CR alloy structural steel, which has excellent hardenability and wear resistance. It also uses synthetic oil and SKF seals for reduced friction. NMRV 075 is lightweight, and its fine appearance makes it suitable for all-around installation. Its self-locking performance also makes it ideal for use in heavy-duty vehicles and heavy-duty equipment. WLY Transmission CO., LTD. is one of the experienced wholesale NMRV 075 Manufacturers in China. We offer high-performance and lightweight aluminum worm gear reducers at competitive prices. OEM is available. Contact us!
