Description This worm gearbox features high efficiency and a self-locking function. Its gapless structure means free maintenance and prevents the lubricant from being easily lost. The pure copper motor allows for low-noise and powerful working, making it suitable for packaging&vending machines, textile&printing&food machinery, office equipment, etc. Key Features Build to Last: Our product uses high-quality cast aluminum and hollow steel tube material and is characterized by heat resistance, wear resistance, high quality, and long service life through die-casting and heat treatment. Powerful Motor: It adopts a single-phase pure copper motor with low loss, low noise, fast heat dissipation, and high return accuracy, which can greatly improve work efficiency. Stable Operation: Both ends of the rotor are equipped with ball bearings, which can reduce friction and temperature during use to ensure stable operation. High Safety: The slow start function can effectively avoid current overshoot and protect the motor. Self-locking Function: With a self-locking function (clockwise/counterclockwise self-locking), the output shaft should not move even when the motor is power-off. High Flexibility: It has a reversing function that is flexible with normally open and closed control systems. Gapless Structure: Its gapless structure means free maintenance that is hermetically sealed. And it prevents the lubricant from easily losing, going bad, and being exchanged. Speed Adjustable: You can match it with a speed controller (not included) to adjust different speeds according to different products to achieve the desired effect. Flexible Installation: This product has been assembled when you receive it. And you can decide the installation place of this gear motor. Details Power Cable: The power cable uses pure copper coils, featuring good conductivity and a large current carrying capacity. Cap: The yellow cap can effectively protect the output bore when not in use. After removing it, you can insert the shaft in the hole. Application It is widely used in automatic barbecue/mixing/doors/windows, conveyor belts, conveyors, feeders, calender, extruders, peeling machines, blenders, cargo lifts, packaging machines, textile/printing/food machinery, vending machines, office equipment, etc. Specifications Type: DM09 Model: NLRV Gearbox: NLRV-040 Color: Gray Material: Cast Aluminum, Hollow Steel Tube Processes: Die-casting, Heat Treatment Shape: Square, Round Feature: Portable Type: DC Motor Gearbox Type: Worm Gearbox Motor: Pure Copper Motor Noise: About 50-60db Output Type: Hollow Bore Torque: 3.66kg/cm Voltage: DC 12V Power: 120W Speed: 1800RPM AMP: 14A Ratio: 1:50 (50K) Input/Output Flange Size: 9*9cm/3.5*3.5inch Output Bore Diameter: 18mm/0.7inch Installation Hole: 7mm/0.27inch Gear Motor Size(L*H): 9*14cm/3.5*5.5inch Connect Interface Size: 9*9cm/3.5*3.5inch Package Size: 30*14.5*10cm/11.8*5.7*3.9inch Net Weight: 5kg/lbs Gross Weight: 5.5kg/lbs Package Included 1* 120W Gear Motor
