Xiaolan Transmission NB090 Helical Planetary Gearbox

MANUFACTURER DOCUMENTATION

Selection checks for NB090 Helical Planetary Gearbox

Use these questions with the manufacturer’s current model sheet and your actual operating conditions.

Specify whether standard, precision or ultra-precision backlash is required: the listing gives limits of 5, 3 and 1 arcmin respectively.
The servo wattage options do not establish torque or mechanical compatibility; ask for the selected ratio, torque rating and motor flange/shaft drawing.
