Commissioning fit for a 40 mm servo axis
The GBX0400160704F is a 40 mm diameter planetary gearbox with a 16:1 reduction ratio, designed to mount directly to a servo motor face — the straight-tooth profile keeps the package short for tight axis layouts. Continuous output torque is 20 N.m at 100 rpm, with a maximum intermittent torque of 32 N.m — enough for indexing tables or pick-and-place Z axes where the duty cycle stays below 60 %. The 28 arc-min maximum torsional backlash means this gearbox suits positioning tasks where absolute accuracy is not the primary spec — think conveyor diverters or rotary cam switches rather than a rotary table with a vision system.
Sourcing reality — obsolete, quoted per project
Available through independent surplus channels; quantities are lot-specific and confirmed at RFQ against the BOM quantity.
Mechanical limits for the install window
Rated axial force on the output shaft is 200 N at 100 rpm for a 10,000-hour life at 30 °C; radial force at mid-shaft is the same 200 N under the same conditions — both derate to 160 N for a 30,000-hour target. The black anodized aluminium housing carries an IP54 rating at the shaft output — splash-resistant but not washdown; keep it inside the cabinet or under a cover on the machine frame. Lubricated for life — no oil-change interval to schedule, which simplifies the spares plan for a commissioning spares kit. Ambient operating range is -25 to 90 °C, covering most production-floor environments without derating.
Efficiency and noise — what the numbers mean on the line
94 % efficiency at rated load means about 6 % of input power is lost as heat in the gear mesh — for a 20 N.m output at 100 rpm that is roughly 12 W thermal load, manageable in free air without a fan. 55 dB at 1 m no-load is quieter than a typical servo drive fan — the gearbox will not be the audible contributor in a panel or on a machine frame.
