40 mm planetary gearbox — 5:1 reduction, 14 N.m continuous
The GBX0400051402F is a 40 mm diameter planetary gearbox from Schneider Electric's GBX series, with a 5:1 reduction ratio and straight-cut teeth. It delivers 14 N.m continuous output torque at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 22 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life and sealed to IP54 at the shaft output — suitable for direct mounting in a clean, dry machine environment where periodic re-lubrication access is not practical.
Torque, backlash, and load ratings — what they mean for fit
The 14 N.m continuous torque at 100 rpm is the design point for steady-state operation; the 22 N.m maximum output torque covers acceleration peaks and short overloads, but sustained running above 14 N.m will reduce service life below the 30,000-hour baseline. Torsional backlash is 24 arcmin — this is a standard-precision grade for positioning applications where repeatability is not critical. For indexing or pick-and-place with tighter registration, a lower-backlash variant (typically <10 arcmin) would be needed. Maximum radial force Fr is 200 N at 100 rpm for 10,000 hours, derating to 160 N for the full 30,000-hour life, with the force applied at mid-distance from the output shaft. Axial force Fa follows the same profile. These limits govern overhung load capacity from pulleys, gears, or couplings mounted directly on the output shaft.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0400051402F as obsolete. No direct replacement or successor order code is published by the manufacturer. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at time of RFQ. For a BOM line that requires this exact 40 mm, 5:1, 14 N.m planetary gearbox, the sourcing posture is quoted-to-order against the required quantity.
Integration notes — mounting, temperature, and lubrication
The gearbox housing is black anodised aluminium, 40 mm external diameter, with a C 45 steel output shaft. Lubricated for life — no maintenance access ports or re-greasing schedule. The IP54 shaft output seal protects against dust ingress and splash, but the gearbox is not rated for washdown or outdoor exposure. Noise level is 55 dB at 1 m, no-load — this is a straight-tooth planetary, so under load the noise floor will rise with torque and speed. For sound-sensitive installations, a helical planetary would run quieter.
