Planetary gearbox, 60 mm, 3:1 — what it delivers
The GBX0600030702F is a straight-tooth planetary gearbox in a 60 mm diameter housing, reduction ratio 3:1, with a continuous output torque of 28 N.m at 100 rpm and a maximum of 45 N.m at the same speed. Efficiency sits at 96 %, and the torsional backlash is held to a maximum of 16 arc.min — a spec that matters when you're reversing direction in a positioning axis and need repeatable zero-point return.
Duty cycle and environmental limits
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient — the gearbox is lubricated for life, so no oil-change interval to schedule. Shaft output carries IP54 protection, meaning it handles dust and splashing water but not submersion; the housing is black anodized aluminium, shaft material C45 steel.
Sourcing reality — obsolete, available through independent channels
Stock is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists from the original manufacturer — a functional equivalent would require a different frame size or ratio.
