What this gearbox delivers
The GBX0400051001F is a 40 mm diameter planetary gearbox from Schneider Electric's GBX series, with a 5:1 reduction ratio and straight-tooth gearing. It's rated for 14 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 22 N.m under the same conditions. Efficiency sits at 94 %, keeping power loss low in the drivetrain. The gearbox is lubricated for life — no field maintenance needed — and the black anodised aluminium housing with C45 steel shaft gives it a straightforward industrial build.
Torque, backlash, and service life at a glance
Continuous torque is 14 N.m at 100 rpm; the maximum allowed torque peaks at 22 N.m at the same speed. Backlash is 24 arcmin — standard for a straight-tooth planetary stage, not a precision zero-backlash unit — so factor that into positioning accuracy budgets. Service life is 30,000 hours at 100 rpm and 30 °C. Radial and axial load limits are 200 N for a 10,000-hour life, dropping to 160 N for the full 30,000-hour run — both applied at mid-distance on the output shaft.
Obsolete — sourcing reality
Schneider Electric lists the GBX0400051001F as obsolete. Available through independent distribution channels; quantities and pricing confirmed at RFQ. For a replacement, look for a 40 mm planetary gearbox with a 5:1 ratio, 14 N.m continuous torque, and 24 arcmin or better backlash. The shaft output IP54 rating and 30,000-hour service life at 100 rpm are the baseline specs to match.
