Lifecycle reality — obsolete, sourced through independent channels
Schneider Electric has marked the GBX0600091001F as obsolete. This part is available through independent surplus and broker channels.
Torque and duty ratings that govern the install
Continuous output torque is 44 N.m (389.4 lbf.in) at 100 rpm and 30 °C ambient — this is the sustained load the gearbox is designed to carry across its 30,000-hour service life. Maximum output torque reaches 70 N.m (619.6 lbf.in) at the same speed and temperature — the short-duration peak the gearbox can handle without damage, not a continuous rating. The 9:1 reduction ratio means the input speed is nine times the output speed; torque multiplication follows the same ratio minus efficiency losses.
Mechanical constraints — backlash, forces, and environment
Maximum torsional backlash is 20 arc.min — this is the angular play at the output shaft under reversing loads. For positioning applications requiring tighter repeatability, a lower-backlash gearbox would be needed. Maximum radial force at the output shaft is 340 N for the 30,000-hour life target, rising to 500 N if the application accepts a 10,000-hour service life. Maximum axial force is 450 N at 30,000 hours, 600 N at 10,000 hours. Shaft output is rated IP54 — protected against dust ingress and splashing water from any direction. The housing is black anodized aluminium; the shaft is C45 steel.
Efficiency and noise — what the numbers mean on the line
Rated efficiency is 94 % — this is the mechanical power throughput from input to output at rated load and speed. The 6 % loss is dissipated as heat within the gearbox; the lubricated-for-life grease handles this without maintenance intervals. Noise level is 58 dB at 1 m, no-load — a typical conversational level. Under load the noise rises with torque; the straight-tooth design is inherently noisier than helical gearing at the same load point. The 30,000-hour service life figure is valid at 30 °C and 100 rpm; higher temperature or speed derates the life.
