NMRV-VS Selection Guide
The NMRV-VS configuration is intended for compact right-angle transmissions that require an input-shaft arrangement. When replacing an existing reducer, confirm the frame size, reduction ratio, input and output shaft dimensions, mounting position, and available installation space before ordering.
What information is needed for selection?
Provide the required output speed or ratio, motor power and speed, load type, operating hours, mounting position, and shaft dimensions. These details help confirm the correct size and service factor.
Is NMRV-VS suitable for replacement projects?
It can be considered for replacement work when the mounting interfaces and operating requirements match. Final selection should be based on the existing gearbox nameplate and dimensional drawing.
Can the shaft and flange be customized?
OEM and ODM options are available for shaft dimensions, flanges, nameplates, finishes, and packaging. Confirm customization requirements before production.
