Product details

160 mm planetary — 8:1 reduction, 450 N.m continuous

The GBX1600080551F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 160 mm housing diameter and an 8:1 reduction ratio. It delivers 450 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent rating of 720 N.m under the same conditions. Torsional backlash is held to 6 arc.min maximum, and torsional rigidity is rated at 38 N.m/arcmin — figures that matter for positioning accuracy in indexing or pick-and-place applications where load reversal occurs.

Load ratings and service life at 100 rpm

Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance oil changes. Maximum axial force (Fa) is 6000 N for the full 30,000-hour life, or 8000 N if the application accepts a 10,000-hour service window. Maximum radial force (Fr) applied at mid-span on the output shaft is 4200 N for 30,000 hours, or 6000 N for 10,000 hours. Efficiency is listed at 94 %, and noise level at 70 dB measured at 1 m under no-load conditions.

Obsolete — sourced through independent channels

Schneider Electric has marked the GBX1600080551F as obsolete. The gearbox is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.

Frequently asked questions

What are the key torque ratings for GBX1600080551F?

Continuous output torque is 450 N.m (3982.8 lbf.in) at 100 rpm and 30 °C. Maximum output torque is 720 N.m (6372.5 lbf.in) under the same conditions. These ratings assume the gearbox is operating within its 30,000-hour service life envelope.

What is the backlash specification on this gearbox?

Maximum torsional backlash is 6 arc.min. Torsional rigidity is 38 N.m/arcmin. For applications requiring tighter positioning repeatability, a lower-backlash planetary series would be needed — this is a standard-precision unit.
