The GBX1200601004F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for applications needing a 60:1 reduction ratio and a continuous output torque of 260 N.m at 100 rpm (30 °C ambient). Maximum output torque reaches 416 N.m under the same conditions — the continuous figure is your duty-cycle anchor; the maximum is for occasional peak loads, not sustained operation. Torsional rigidity is 12 N.m per arcmin — this tells you how much the output shaft twists under load, relevant for positioning accuracy in indexing or servo-feed axes. Maximum torsional backlash is 14 arc.min — the angular play in the gear train before the output engages, a key spec for reversing or start-stop cycles where lost motion affects repeatability.
Mechanical limits and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no oil-change interval to schedule, but the life rating assumes the load stays within the continuous torque envelope. Maximum axial force (Fa) on the output shaft is 2,100 N for the 30,000-hour life target, or 2,800 N if you accept a shorter 10,000-hour service life — both at 100 rpm and 30 °C. Maximum radial force (Fr) is 1,500 N for 30,000 hours, rising to 2,000 N for 10,000 hours — force applied at mid-distance from the output shaft, so belt-drive or chain-sprocket overhung loads need to stay within these limits. Ambient temperature range for operation is -25 to 90 °C — the lubricant and seal materials are specced for that band, but the torque ratings are quoted at 30 °C; derate above that.
Construction and environmental sealing
Housing is black anodized aluminium with a 120 mm external diameter — the shaft output carries an IP54 rating, meaning dust-protected and splash-resistant at the seal face, but not submersible. Shaft material is C45 carbon steel — standard for this class, with adequate hardness for keyed or shrink-disc connections. Noise level is 65 dB at 1 m, no-load — a moderate figure for a 60:1 planetary stage; expect a few dB higher under full torque. Efficiency is listed at 94 % — typical for a single-stage planetary with straight teeth; the remaining 6 % is frictional and churning loss, which shows up as heat in the housing.
Lifecycle reality — obsolete, sourced on request
No official successor or cross-reference is recorded from the manufacturer — this is a straight-to-surplus-channel part. Sourced through independent distribution against an RFQ — quantities are lot-specific and confirmed at quote time; no blanket stock claim.
