Planetary gearbox — 60 mm frame, 8:1 reduction
The GBX0600081002F is a 60 mm diameter planetary gearbox from Schneider Electric's GBX series, offering an 8:1 reduction ratio. It delivers 18 N.m continuous output torque at 100 rpm and 30 °C, with a maximum peak of 29 N.m under the same conditions. Rated service life is 30,000 hours at rated load, and the unit is lubricated for life — no maintenance re-greasing interval to schedule.
Torque, backlash, and force limits
Continuous torque is 18 N.m; maximum torque hits 29 N.m — the margin above continuous covers acceleration peaks and momentary overloads, not sustained duty. Maximum torsional backlash is 16 arc.min, which governs positioning repeatability in indexing or pick-and-place applications. Axial force limit is 450 N for the full 30,000-hour life, stepping to 600 N if you accept a 10,000-hour service window. Radial force at mid-shaft is 340 N for 30,000 hours, 500 N for 10,000 hours. These are the bearing-life constraints — overshoot them and the gearbox wears out ahead of the rated life.
Efficiency, noise, and environmental ratings
Efficiency is 94 % — typical for a single-stage planetary with straight teeth at this ratio. Noise level is 58 dB at 1 m, no-load, which is quiet enough for indoor machinery without enclosure. Shaft output seal is rated IP54, so the gearbox handles dust and splashing water at the output shaft — not submersion, but fine for washdown-adjacent areas. Housing is black anodized aluminium; shaft material is C45 steel.
Obsolete — sourcing through independent channels
Schneider Electric lists this gearbox as obsolete. No official successor or cross-reference is recorded from the manufacturer. Sourcing runs through independent surplus and broker channels; quantities are confirmed at RFQ against the specific BOM line. For a replacement, a 60 mm planetary with 8:1 ratio and 18 N.m continuous torque from another manufacturer will need a different mounting interface — the GBX frame dimensions and bolt pattern are proprietary. A board or bracket spin is likely.
