The GBX1600151001F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for a 160 mm output-stage diameter and a 15:1 reduction ratio. That ratio multiplies motor torque by 15 while cutting output speed by the same factor — a common match for servo or induction motors driving indexing tables, conveyors, or positioning axes where you need high torque at low rpm without a belt stage. Continuous output torque is 700 N.m at 100 rpm and 30 °C, with a peak (maximum) of 1120 N.m for short-duration loads. The 94 % efficiency means only 6 % of the input power is lost as heat through the gear mesh — a solid figure for a straight-tooth planetary, where efficiency typically runs 90–96 % depending on ratio and lubrication. Backlash is held to 10 arc.min maximum — that's the angular play between input and output when the direction reverses. For a positioning axis with a ball screw, 10 arc.min at the gearbox translates to a few hundredths of a millimetre of lost motion at the load, which is acceptable for many pick-and-place or material-handling cycles but not for sub-arcminute precision stages.
Load ratings and service life — sizing the gearbox for real duty
Service life is rated 30,000 hours at 100 rpm and 30 °C ambient — that's about 3.4 years of continuous 24/7 operation at that speed. The gearbox is lubricated for life, so no oil-change intervals; the sealed grease pack is meant to last the full service window. Maximum axial force (Fa) on the output shaft is 6000 N for the full 30,000-hour life, or 8000 N if you accept a shorter 10,000-hour life. Radial force (Fr) at mid-shaft is 4200 N for 30,000 hours, 6000 N for 10,000 hours. These numbers govern how much belt tension or overhung load the output bearing can take — a direct-coupled motor or a timing-belt pulley must stay within these limits or the bearing life drops fast. Torsional rigidity is 41 N.m/arcmin — that's the stiffness of the gear train under load. A 41 N.m torque twist produces 1 arcmin of wind-up. For a servo axis with high dynamic response, higher stiffness (lower wind-up) means less phase lag in the position loop; 41 N.m/arcmin is typical for a 160 mm-frame planetary at this ratio.
Lifecycle reality — obsolete, sourced through surplus channels
Schneider Electric lists the GBX1600151001F as obsolete. That means the factory no longer builds it, and there is no direct OEM stock. The gearbox is available through independent surplus and broker channels — quantities are lot-specific, and each unit is confirmed at RFQ time. If you need a drop-in replacement, the closest functional match is another 160 mm-frame planetary with a 15:1 ratio and 700 N.m continuous torque from the same GBX family — but the exact order code depends on the backlash grade and shaft configuration. A sourcing specialist can cross-reference the BOM position against current GBX catalog numbers. Because this is a discontinued part, the price and availability are quoted per RFQ. The condition is typically new-in-box surplus or pulled from cancelled orders — the sealed lubrication and black anodized aluminium housing mean storage life is long if the shaft seals are intact.
Environmental and mechanical fit — IP54, temperature range, shaft material
The shaft output carries an IP54 rating — dust-protected and splash-resistant, but not submersible. That suits indoor machine builds (conveyor drives, packaging lines, material handling) where occasional coolant mist or washdown spray hits the output seal. The ambient operating range is -25 to 90 °C, covering most factory-floor conditions without a heater or cooler.
