NRV-FA Series Shaft Input Worm Gearbox with Output Flange adopts a compact worm gear transmission structure combined with direct shaft input and output flange design. It provides flexible drive connection, convenient equipment integration, smooth operation and reliable torque transmission. The output flange structure simplifies the connection between gearbox and driven equipment, making it suitable for industrial applications requiring compact installation, high reduction ratios and stable low-speed operation. With a typical output torque range of 10–1,500 N·m and power range of 0.06–15 kW, it is widely used in conveyors, automation equipment, packaging machinery and material handling systems.
