80 mm planetary gearbox — 15:1 reduction, 110 N.m continuous
The GBX0800150704F is a straight-tooth planetary gearbox from Schneider Electric, 80 mm external diameter, with a 15:1 reduction ratio. It delivers 110 N.m continuous output torque at 100 rpm and 30 °C, and can handle up to 176 N.m peak under the same conditions. Rated efficiency is 94 %, with a noise level of 60 dB at 1 m under no-load — quiet enough for most production-floor environments without additional acoustic enclosures.
Mechanical ratings and load capacity
Maximum torsional backlash is 14 arc.min — this is a standard-precision grade, not a zero-backlash unit. For positioning applications requiring tighter repeatability, a preloaded or low-backlash series would be needed. Service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life — no maintenance re-greasing interval. Maximum axial force (Fa) is 1200 N at 100 rpm for 10,000 hours, derating to 900 N for the full 30,000-hour life. Maximum radial force (Fr) applied mid-span on the output shaft is 650 N for 30,000 hours, or 950 N for 10,000 hours. Shaft output is rated IP54 — protected against dust ingress and splashing water, but not submersion. Ambient operating range is -25 to 90 °C.
Construction and materials
Housing is black anodized aluminium; shaft material is C45 carbon steel. The straight-tooth spur gear set is a cost-effective design for moderate torque and speed, though it produces more audible whine than helical at higher rpm — the 60 dB noise figure confirms it stays within typical industrial limits.
Lifecycle and sourcing
Schneider Electric lists this gearbox as obsolete. The part is available through independent distribution channels; quantities are confirmed at RFQ against the BOM line.
