Torque and duty-cycle constraints
The GBX0800150553F is a planetary gearbox with straight teeth, 80 mm outer diameter, and a 15:1 reduction ratio. Its continuous output torque is 973.6 lbf.in (110 N.m) at 100 rpm and 86 °F (30 °C), with a maximum output torque of 1557.7 lbf.in (176 N.m) under the same conditions — the margin above continuous is the overload headroom for transient peaks, not sustained operation. Service life is rated at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance interval for oil changes, which simplifies the BOM for sealed-drive assemblies.
Mechanical ratings and environmental fit
Maximum torsional backlash is 14 arc.min — this is the angular play at the output shaft under reversing loads. For positioning applications requiring less than 0.5° cumulative error, a lower-backlash gearbox (e.g. 5 arc.min or less) would be specified; 14 arc.min suits indexing and conveyor drives where reversal accuracy is not critical. Maximum axial force Fa is 1200 N at 100 rpm for a 10,000-hour service life, derating to 900 N for the full 30,000-hour rating. Maximum radial force Fr is 950 N at 100 rpm (10,000-hour life) and 650 N at 30,000 hours, both applied at mid-distance from the output shaft. These limits govern the overhung load from a belt pulley or chain sprocket — exceeding them reduces bearing life below the stated service hours. Ambient temperature range is -13 to 194 °F (-25 to 90 °C), covering most indoor industrial enclosures and outdoor cabinet installations. The shaft output seal is rated IP54, meaning protection against dust ingress and splashing water — suitable for dry indoor environments but not washdown or submerged service.
Efficiency and noise floor
Efficiency is listed at 94 %, which is typical for a single-stage planetary gearbox at full load. The noise level is 60 dB at 1 m, no-load — this is the acoustic baseline without load-induced gear mesh harmonics; under load the level rises with torque and speed.
Lifecycle status and sourcing
Per the manufacturer's record, the GBX0800150553F is classified as Obsolete. Sourcing is through independent distribution channels; quantities are confirmed at RFQ against the specific BOM line. The shaft material is C 45 steel (medium-carbon, through-hardened), and the housing is black anodized aluminium. These materials are standard for this class of gearbox and do not limit the part's compatibility with common motor flanges or mounting brackets.
