Lifecycle status: obsolete, replacement is a different frame
Schneider Electric lists GBX1200160843D as obsolete, so the unit is no longer in factory production and the official channel no longer cuts new units to order.
What the frame delivers: 16:1 in a 120 mm planetary housing
GBX1200160843D is a planetary gearbox in the Schneider GBX family with a 120 mm external diameter and a 16:1 reduction, intended to bolt directly between a servo or stepper and the driven load. Maximum torsional backlash is 12 arc.min and torsional rigidity is 13 N.m/arcmin, so the gearbox introduces measurable wind-up under step changes in load — fine for conveyors and rotary indexing, but a positioning application that needs sub-arc-minute repeatability will need a tighter unit on its BOM line.
Shaft loads are tied to the 30,000-hour service life
Service life is rated 30000 h at 100 rpm at 30 °C, which means the published shaft load figures are not constants — they shift with the speed-and-life point on the duty curve. Maximum radial force Fr is 1500 N at 100 rpm applied at mid-distance from the output shaft over the 30000 h life, rising to 2000 N if the design point drops to 10000 h at 100 rpm — pulleys and pinions mounted outboard of mid-shaft force the buyer toward a shorter-life budget or a redesigned mount. Maximum axial force Fa is 2100 N at 100 rpm over the 30000 h life and 2800 N over 10000 h at 100 rpm, so any thrust from a helical-bevel pinion or a screw-driven load needs to be checked against this envelope before the coupling is selected.
Operating envelope and sealing
Ambient temperature for operation is -25...90 °C, mounting position is any position, and the housing is black anodized aluminium — the gearbox can be oriented to suit the machine layout without re-specifying grease. The shaft output carries IP54 protection, which keeps splashing water out of the seal lip but does not suit a washdown cell — a food-grade or outdoor deployment should plan a local guard or a higher-rated cover over the output seal. Noise level is 65 dB at 1 m no-load and efficiency is 94 %, so the gearbox runs quieter than an equivalently sized helical-bevel unit but still sheds about 6 % of input power as heat that has to leave the housing through its anodized surface.
Sourcing posture: independent channel only
For a buyer planning a multi-year line, think landed, not list — duty, Incoterms, and freight on an obsolete part can swing the total cost well past the unit figure, and the paperwork has to be clean because the original factory declaration is no longer refreshed.
