What this gearbox delivers — 60 mm planetary, 5:1, 40 N.m continuous
The GBX0600051002F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 5:1 reduction ratio and straight-cut teeth. It delivers a continuous output torque of 40 N.m (354.03 lbf.in) at 100 rpm and 30 °C, and can handle a maximum output torque of 64 N.m (566.4 lbf.in) under the same conditions. Efficiency is listed at 94 %, and the noise level at 58 dB measured 1 m away under no-load — quiet enough for most machine-tool or conveyor drives without an enclosure. The housing is black anodized aluminium (60 mm OD), the shaft is C45 steel, and the shaft output seal is rated IP54 — splash-resistant but not washdown-rated.
Torque, life, and backlash — the numbers that matter for fit
Continuous torque is 40 N.m at 100 rpm and 30 °C; maximum torque is 64 N.m at the same speed and temperature. The rated service life is 30,000 hours at those conditions, and the gearbox is lubricated for life — no maintenance interval to schedule. Maximum torsional backlash is 16 arc.min — standard precision for a straight-tooth planetary, not a zero-backlash unit. Torsional rigidity is 2.3 N.m/arcmin, which tells you how much wind-up to expect under load. Maximum axial force (Fa) is 450 N at 100 rpm for the 30,000-hour life target, or 600 N if you accept a 10,000-hour service life. Maximum radial force (Fr) is 340 N at mid-shaft for 30,000 hours, 500 N for 10,000 hours. These are the limits that govern bearing life in an overhung-load application like a belt or chain drive.
Obsolete — what that means for sourcing
Schneider Electric lists the GBX0600051002F as obsolete. For a line-down or BOM-fill situation, the part is sourced through independent surplus channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or mounting-compatible direct replacement is documented by Schneider, so a substitution would require checking the mounting flange, shaft diameter, and input interface against whatever planetary gearbox you are considering as a swap.
