The GBX0400151402F is a 40 mm planetary gearbox with a 15:1 reduction ratio, straight teeth, and a continuous output torque of 18 N.m at 100 rpm. That continuous rating is the number to size against — the maximum output torque of 29 N.m is a short-duration peak, not a steady load. Efficiency sits at 94 %, which is typical for a single-stage planetary of this size — the loss goes into heat, so the housing (black anodized aluminium) acts as the heatsink. The shaft output carries an IP54 rating, meaning it's protected against dust ingress and splashing water, but not submersion or high-pressure washdown. Service life is specified at 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no maintenance oil changes. Backlash is 28 arcmin maximum, which is standard for a commercial planetary; if your application needs tighter positioning, you'd step to a low-backlash or precision series.
