15:1 planetary — what the ratings mean on a real line
The GBX0600151402F: This is a 60 mm-diameter planetary gearbox with a 15:1 reduction ratio, straight-cut teeth, and a continuous output torque of 44 N.m at 100 rpm — that's the working limit for steady-state positioning or conveying loads, not the peak figure. The maximum output torque hits 70 N.m at the same speed, but that's for occasional peak loads, not sustained duty — the 30,000-hour service life rating at 100 rpm and 30 °C is tied to the continuous 44 N.m figure. Torsional backlash is 20 arcmin maximum, which puts this in the standard-precision class — adequate for general indexing or conveyor drives, but not for a servo positioning loop that needs single-arcmin repeatability.
Obsolete — sourcing reality for a decommissioned line
Available through independent surplus and broker channels, typically pulled from decommissioned lines or overstock. Quantities are lot-specific; availability and pricing confirmed at RFQ. For a line-down replacement, the closest functional match would be another 60 mm-frame planetary gearbox with a 15:1 ratio and at least 44 N.m continuous torque — but the mounting flange, input shaft diameter, and keyway must be verified against the existing installation.
Load limits and environmental fit
The shaft output carries an IP54 rating — splash-proof from the shaft side, but the gearbox body itself is not sealed for washdown. The housing is black anodized aluminium; the shaft is C45 steel. Maximum axial force on the output shaft is 450 N for the full 30,000-hour service life at 100 rpm and 30 °C, or 600 N if you accept a shorter 10,000-hour life. Radial force limits are 340 N and 500 N respectively, measured at mid-shaft. Operating ambient range is -25 to 90 °C, and the gearbox is lubricated for life — no oil changes or regreasing intervals.
Efficiency and noise — thermal and acoustic budget
Listed at 94% efficiency, which means roughly 6% of the input power turns into heat inside the gearbox — at 44 N.m output and 100 rpm (about 460 W mechanical), that's around 28 W of heat to dissipate through the 60 mm aluminium housing. Noise level is 58 dB at 1 m under no-load conditions — quiet enough for most production floor environments, but the figure will rise under load and with wear over the 30,000-hour service life.
