Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0400150553F as obsolete.
15:1 reduction, 18 N.m continuous — what the ratings mean
The GBX0400150553F is a 40 mm diameter planetary gearbox with a 15:1 reduction ratio. Continuous output torque is 18 N.m at 100 rpm and 30 °C; maximum output torque reaches 29 N.m under the same conditions. The 28 arc-min maximum torsional backlash is a standard precision grade for positioning applications where repeatability matters more than absolute accuracy — think indexing tables or pick-and-place axes, not servo-grade contouring. Efficiency is listed at 94 % — typical for a single-stage planetary with straight teeth at this ratio. The 55 dB noise level at 1 m, no-load is quiet enough for lab or light assembly environments; under load the noise will rise with torque and speed.
Mechanical limits and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no maintenance re-greasing interval. Maximum axial force on the output shaft is 200 N for a 10,000-hour life, derating to 160 N for the full 30,000-hour target. Radial force follows the same pattern: 200 N at mid-shaft for 10,000 hours, 160 N for 30,000 hours. These limits govern belt-drive or overhung-load applications — a direct-coupled motor avoids the radial load concern entirely. Shaft output sealing is IP54 — splash protection, not washdown. The housing is black anodized aluminium; the output shaft is C45 steel. Operating ambient range is -25 to 90 °C.
