Planetary gearbox with 16:1 reduction — torque and backlash limits
The GBX0600161001F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 60 mm external diameter, delivering a 16:1 reduction ratio. Continuous output torque is 44 N.m at 100 rpm and 30 °C ambient; maximum intermittent torque reaches 70 N.m under the same conditions. Maximum torsional backlash is 20 arc.min — this is the angular play under reversal, which governs positioning repeatability in indexing or servo applications. For a 16:1 gearbox this is a standard commercial-grade tolerance; precision classes typically run below 10 arc.min.
Shaft loading and environmental limits
Rated axial force Fa is 450 N for a 30,000-hour service life at 100 rpm and 30 °C, or 600 N for a 10,000-hour life. Radial force Fr at mid-span on the output shaft is 340 N for 30,000 hours, 500 N for 10,000 hours. These limits must be respected in the coupling and driven-load design to avoid premature bearing failure. The shaft output seal carries IP54 protection — suitable for dry indoor environments with dust ingress control, but not rated for washdown or direct spray. Operating ambient range is -25 to 90 °C, which covers most panel and machine-enclosure conditions. The gearbox is lubricated for life, eliminating periodic oil changes. Service life is 30,000 hours at rated torque and speed — approximately 3.4 years of continuous operation — after which replacement is expected.
Efficiency and noise — energy loss and operator environment
Stated efficiency is 94 % at rated load, meaning 6 % of input power is lost as heat in the gear mesh and bearings. For a 44 N.m output at 100 rpm (about 460 W mechanical), the thermal loss is roughly 28 W — this must be dissipated through the aluminium housing and mounting interface. Noise level is 58 dB at 1 m under no-load conditions. This is comparable to a quiet office environment and typically does not require additional acoustic enclosure in machine design.
Sourcing — obsolete, quoted to order
Schneider Electric has marked the GBX0600161001F as obsolete. No direct successor order code is listed on the manufacturer's lifecycle record. Availability is through independent distribution channels; quantities are confirmed at RFQ against the specific BOM line. For volume procurement or last-time-buy requirements, the part is sourced to order.
