Its continuous output torque is 110 N.m at 100 rpm and 30 °C, with a peak capability of 176 N.m under the same conditions — the margin between continuous and maximum tells you the overload headroom for acceleration transients or short-duration peak loads. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this size; the 6 % loss is mostly gear mesh friction and churning losses in the lifetime grease fill. The 9 arc.min maximum torsional backlash means the output shaft position can lag the input by up to 9 minutes of arc under load reversal — relevant for positioning accuracy in indexing or pick-and-place axes where cumulative backlash eats into the repeatability budget. ## Noise, life, and shaft loading — the operating envelope Noise output is 60 dB at 1 m, no-load — a moderate level that allows the gearbox to run in a cabinet without acoustic treatment, but the figure will rise under load and at higher speeds. Service life is 30,000 hours at 100 rpm and 30 °C, which is the L10 life for the bearings and gear contact; the gearbox is lubricated for life, so no maintenance interval for oil changes. Maximum axial force on the output shaft is 1200 N for a 10,000-hour life at 30 °C, dropping to 900 N for the full 30,000-hour rating; radial force is 950 N and 650 N respectively, applied at mid-shaft. These limits govern overhung load from pulleys, sprockets, or direct-coupled loads. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX0800050551F as obsolete. The gearbox is available through independent surplus and distribution channels; quantities are lot-specific and confirmed at RFQ against your BOM line.","metaTitle":"Schneider Electric GBX0800050551F Planetary Gearbox, 5:1","metaDescription":"Schneider Electric GBX0800050551F planetary gearbox, 80 mm, 5:1 ratio, 110 N.m continuous torque, 94 % efficiency.
