NMRV030 Worm Reducer Round vs Square Flange Dimension Comparison

The NMRV030 round flange (B14) features compact outer diameter, ideal for narrow-space servo motor vertical mounting. The NMRV030 square flange (B5) provides larger mounting span, more stable for fixed-base installation on mini conveyor and positioning machines.

Check our attached dimension chart to verify flange outer size, bolt hole distance and input bore tolerance. Choose the correct flange type to avoid assembly mismatch and ensure long-term stable low-noise operation.
