40 mm planetary gearbox — 16:1 reduction, 20 N.m continuous
The Schneider Electric GBX0400160702F is a straight-tooth planetary gearbox with a 40 mm housing diameter and a 16:1 reduction ratio, delivering 20 N.m continuous output torque at 100 rpm and 30 °C ambient. Rated efficiency is 94 %, with a noise floor of 55 dB measured at 1 m under no-load conditions — relevant for noise-sensitive production environments where the gearbox runs near the drive train.
Torque, life, and load ratings — what they mean for a motion axis
Continuous output torque is 20 N.m at 100 rpm and 30 °C; maximum output torque reaches 32 N.m under the same conditions — the margin between continuous and peak is 12 N.m, which governs acceleration and intermittent overload capability in the application. Service life is specified at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no re-greasing interval to schedule in the PM plan. Maximum radial force Fr is 200 N applied at mid-distance from the output shaft for a 10,000-hour life, derating to 160 N for the full 30,000-hour target; axial force Fa follows the same 200 N / 160 N profile at the same duty points.
Obsolete — sourcing through independent channels
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or dimensionally identical replacement exists within the current GBX family — a new gearbox selection and possibly a mounting adaptor are required for new builds.
