Planetary gearbox, 60 mm, 5:1 reduction
The GBX0600050551F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 60 mm diameter, with a 5:1 reduction ratio. It delivers 40 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 64 N.m under the same conditions. Rated efficiency is 94 %, and the no-load noise level is 58 dB measured at 1 m — figures that matter when the gearbox runs in a quiet production area or near operator stations.
Torque, life, and load limits
Continuous output torque is 40 N.m (354 lbf.in) at 100 rpm and 30 °C; the maximum output torque reaches 64 N.m (566.4 lbf.in) at the same speed and temperature. Service life is rated at 30,000 hours under these conditions. Maximum axial force on the output shaft is 450 N for the 30,000-hour life target, or 600 N if the application accepts a 10,000-hour service life. Radial force limits are 340 N and 500 N respectively, with the force applied at mid-distance from the output shaft. Torsional rigidity is 2.3 N.m/arcmin, and maximum torsional backlash is 16 arc.min — the latter sets the positioning repeatability floor for indexing or pick-and-place axes.
Construction and environmental ratings
Housing is black anodized aluminium; the output shaft is C45 steel. The gearbox is lubricated for life, so no maintenance schedule for oil changes. Shaft output seal is rated IP54 — suitable for indoor use where dust and splash are present, but not for washdown or submersion.
Lifecycle and sourcing
Schneider Electric lists the GBX0600050551F as obsolete. Available through independent surplus channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement from Schneider — a functional equivalent would require verifying mounting dimensions, shaft size, and torque ratings against the application.
