Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0400091001F as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific; availability and pricing confirmed at RFQ against your BOM line.
Torque and duty cycle that matter
Continuous output torque is 16.5 N.m at 100 rpm and 30 °C — this is the rating that governs steady-state operation, not the peak figure. Maximum output torque reaches 26 N.m under the same conditions, but that's the short-duration ceiling before the gear train sees accelerated wear. Service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life. That's a solid MRO spare horizon for a machine that runs one shift; for continuous 24/7 duty, budget a replacement at roughly 3.4 years.
What the 9:1 reduction and straight teeth mean for fit
The 9:1 ratio is a common speed-reduction step for indexing tables, conveyor drives, and small positioning axes where the motor runs 900–1800 rpm and the output needs 100–200 rpm. Straight teeth (spur) are simpler and more efficient than helical — 94 % efficiency on this unit — but they generate more audible noise than helicals at the same load. Maximum torsional backlash is 28 arc.min — this is a standard-precision gearbox, not a zero-backlash servo unit. For positioning applications that reverse direction, the lost motion at the output will be visible; for constant-direction loads like conveyors, it's irrelevant.
Mounting and environmental limits
40 mm external diameter, black anodized aluminium housing, C45 steel shaft. Shaft output seal is rated IP54 — splash-resistant but not submersible. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments but not washdown zones. Maximum axial force on the output shaft is 200 N for 10,000 hours at 30 °C, derating to 160 N for the full 30,000-hour service life. If your application imposes axial loads (e.g., a leadscrew or thrust bearing), stay below the lower figure for the rated life.
