What the 8:1 reduction and 18 N.m mean for your axis
The GBX0600081001F: This is a straight-tooth planetary gearbox with an 8:1 reduction ratio — it multiplies motor torque by eight while cutting output speed by the same factor, a common ratio for indexing tables and conveyor drives where you need position holding without a brake. Continuous output torque is 18 N.m at 100 rpm; maximum intermittent torque reaches 29 N.m at the same speed. The 94 % efficiency means only 6 % of input power is lost to friction and windage — that keeps the thermal rise low enough that the gearbox runs without external cooling. Service life is rated 30,000 hours at 100 rpm and 30 °C ambient — roughly 3.4 years of continuous operation. The unit is lubricated for life, so no oil-change schedule to track in a PM plan.
Mounting and environmental fit
The housing is black anodized aluminium, 60 mm external diameter — a compact envelope that fits into tight axis assemblies. Shaft output is protected to IP54, meaning it handles dust and splashing water but not washdown; keep it inside a cabinet or under a cover in wet environments. Ambient operating range is -25 to 90 °C, so it works in unheated plant bays and near ovens as long as radiated heat stays below the ceiling. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if you accept a shorter 10,000-hour service interval. Noise level is 58 dB at 1 m under no-load — quiet enough for operator-adjacent stations without acoustic enclosures. The C 45 steel shaft is standard induction-hardened medium-carbon steel, adequate for keyed or clamped couplings.
Sourcing an obsolete planetary gearbox
For a line-down situation, the unit is sourced through independent distribution channels; quantities are confirmed at RFQ. The 60 mm body diameter, 8:1 ratio, and 18 N.m continuous torque are the critical fit parameters when evaluating a functional alternative.
