NMRV Series Worm Gearbox — Specifications

NMRV — Technical Specifications Overview

This page presents the engineering specifications for the CHINFAR NMRV. Complete selection data — including frame sizes, gear ratios, output torque, service factors, and dimensioned shaft drawings — is available from our technical team upon request.

Operating envelope

• Power range and speed envelope (provided after model and duty confirmation)
• Permissible radial and axial loads on output shaft
• Ambient temperature range and altitude derating
• Duty cycle classification per IEC / GB standard

Dimensional reference

Standard NMRV units follow CHINFAR's unified shaft height and mounting interface, with direct dimensional compatibility with widely used international gearbox series. Reference dimensions are published in our datasheet (PDF available on request).
