Product Introduction
The 2-Stage NMRV 63 – 75 Gearbox is an ultra-powerful drive assembly, standing out with its ability to create extremely large gear ratios and superior torque enhancement for industrial systems.
Warranty up to 24 months – Fast nationwide delivery – Dedicated technical support.
The 2-Stage NMRV 63 – 75 Gearbox is a gearbox series formed by combining two NMRV gearboxes of sizes 63 and 75, creating a powerful drive assembly with extremely high speed reduction capability and superior torque enhancement.
Thanks to this special coupling design, the 2-stage gearbox perfectly meets the requirements of industrial systems needing low rotational speed, high pulling force, and high stability with common gear ratios from 1/150 to 1/10,000. This is an ideal choice for applications requiring precise, durable, and energy-efficient transmission.
The 2-stage NMRV gearbox is designed compactly, exquisitely, and with high finishing quality, easily installed in limited spaces. The housing is made of monolithic die-cast aluminum alloy, providing lightweight, high mechanical strength, and fast heat dissipation during operation.
Inside, the worm shaft and worm gear assembly is precisely machined, ensuring smooth meshing, minimizing noise and friction. This helps the 2-Stage NMRV 63 – 75 Gearbox operate smoothly, save energy, and have a long service life even in continuous working environments.
The 2-Stage NMRV 63 – 75 Gearbox is composed of two standard NMRV gearboxes, in which the output shaft of the NMRV 63 gearbox is directly connected to the input shaft of the NMRV 75 gearbox through an intermediate coupling. With the following structure:
The parameters below provide information on dimensions, shafts, and installation capabilities of each gearbox stage.
NMRV 63 is the first drive stage, receiving motion from the motor and transmitting power to NMRV 75.

Thanks to its flexible working capability and high transmission efficiency, the 2-Stage NMRV 63 – 75 Gearbox is commonly applied in many fields such as:
To install the 2-stage NMRV gearbox according to technical requirements, follow the steps below:
Step 1: Pre-installation inspection
Compare the model, gear ratio, mounting type, shaft diameter, and flange dimensions of the gearbox with the motor. Check bolt fastening positions and the external condition of the equipment before assembly.
Step 2: Connecting the gearbox to the motor
Insert the motor shaft into the input shaft of the gearbox, align the flange so that the two contact surfaces meet evenly. Then tighten the bolts in order to secure the drive assembly.
Step 3: Checking the assembly
Check the coaxiality between the motor and gearbox, the tightness of the bolts, and the contact positions of the flange. Ensure the assembled unit is in the correct position before operation.
Step 4: Operational inspection
Run the system at no-load mode for a short time, monitor noise, vibration, and check the joint positions to detect abnormal signs or oil leaks.
