The GBX0600200702F is a 60 mm-diameter planetary gearbox with a 20:1 reduction ratio, delivering 44 N.m continuous output torque at 100 rpm and 30 °C ambient. That 44 N.m is the rating for sustained duty — the maximum output torque reaches 70 N.m for intermittent peaks, but the continuous figure governs thermal stability in a cycle. Straight-tooth planetary design means lower cost and higher efficiency (94 %) than helical, but with more audible noise — the no-load reading is 58 dB at 1 m, which is audible in a quiet cabinet but acceptable on a production floor.
Backlash, service life, and the limits that matter for fit
Maximum torsional backlash is 20 arc.min — standard precision for a commercial planetary stage. If your application needs less than 10 arc.min for positioning accuracy, this gearbox is not the right fit. Rated service life is 30,000 hours at 100 rpm and 30 °C, lubricated for life with no maintenance interval. The shaft output seal is IP54 — splash-resistant but not washdown-rated; the housing is black anodized aluminium with C45 steel shafts. Maximum radial force on the output shaft is 340 N at mid-span for the 30,000-hour life target, rising to 500 N if you accept a 10,000-hour service life. Axial force limits are 450 N and 600 N respectively. These are the numbers that determine bearing survival in a belt-drive or overhung-load application.
Obsolete — sourcing the GBX0600200702F today
Schneider Electric lists this gearbox as obsolete. The GBX series is closed; the replacement path is a different planetary family with a different mounting interface — a bracket or adapter plate is likely needed. Sourced through independent distribution against an RFQ. Quantities are confirmed at quote time; no stock-holding claim. If you are supporting an installed machine with this gearbox, buying a spare while lots are still findable is the prudent move — no spare, no sleep.
