Product details

Torque and duty cycle for the BOM

The GBX0800250853G: Continuous output torque is 110 N.m at 100 rpm at 30 °C; maximum output torque hits 176 N.m at the same speed and temperature — the margin above continuous covers acceleration peaks and short overloads without oversizing the next stage. Service life is rated 30000 h at 100 rpm and 30 °C, with the gearbox lubricated for life — no oil changes on the maintenance schedule.

What the 25:1 reduction and backlash mean on the line

Straight-tooth planetary with a 25:1 reduction ratio; maximum torsional backlash is 14 arc.min — that's the angular slop between input and output when reversing direction, so for a pick-and-place or indexing axis you'll want to check whether 14 arc.min is tight enough for the positioning tolerance. Torsional rigidity is 6.5 N.m/arcmin — this tells you how much the gearbox winds up under load. At 110 N.m continuous, expect about 17 arcmin of elastic wind-up before the backlash gap closes.

Mounting and environmental fit

Mounts in any position, which simplifies layout in a tight cabinet or on a machine frame. Shaft output seal is IP54 — fine for dry indoor environments but not for washdown; keep it away from direct spray. Ambient operating range is -25 to 90 °C, so it handles unheated warehouses and close-to-motor heat soak. Black anodized aluminium housing with C45 steel shaft — standard industrial corrosion protection.

Frequently asked questions

What is GBX0800250853G's listed efficiency?

Efficiency is listed at 94 %. For a straight-tooth planetary at 25:1 reduction, that is a typical figure — the power loss goes into heat in the gear mesh, not into the housing.

What is the noise level on this gearbox?

Noise level is 60 dB at 1 m, no-load. That is about the level of a quiet office — audible but not intrusive in a machine room with other rotating equipment.
