Planetary gearbox with 15:1 reduction and 110 N.m continuous torque
The GBX0800150551F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with an 80 mm outer diameter and a 15:1 reduction ratio. It delivers 110 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent rating of 176 N.m under the same conditions. Rated efficiency is 94 %, meaning roughly 6 % of input power is lost as heat through the gear train — typical for a single-stage planetary with straight teeth at this ratio. Noise measures 60 dB at 1 m under no-load, which is quiet enough for most production-floor environments without enclosure treatment.
Torque, load ratings, and service life at 100 rpm
Continuous torque is 110 N.m (973.6 lbf.in); maximum output torque hits 176 N.m (1557.7 lbf.in) for intermittent peaks. The 30,000-hour service life at 100 rpm and 30 °C is the design baseline — push the duty cycle or ambient temperature and the L10 life shortens accordingly. Maximum axial force (Fa) on the output shaft is 1200 N for 10,000 hours at 100 rpm and 30 °C, derating to 900 N for the full 30,000-hour life. Radial force (Fr) applied at mid-span on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours. These are the hard limits for overhung load applications like belt drives or pinion gears. Torsional rigidity is 6.5 N.m/arcmin — the gearbox twists 1 arcminute per 6.5 N.m of applied torque. Maximum torsional backlash is 14 arcmin, which sets the positioning repeatability floor for indexing or servo applications.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0800150551F as obsolete. No official successor or cross-reference is recorded — the GBX series has been superseded by newer planetary families with different mounting interfaces and backlash specs. Available through independent surplus and broker channels. Quantities are lot-specific; pricing and lead time confirmed at RFQ against your BOM line. No stock-holding claim — sourced per order.
Build and environmental specs
Housing is black anodized aluminium; output shaft is C45 carbon steel. Shaft output seal is rated IP54 — splash-proof but not submersible. The gearbox is lubricated for life, so no oil-change interval in the maintenance schedule. Ambient operating temperature spans -25 °C to 90 °C (-13 °F to 194 °F). Single-unit packaging.
