The GBX0600320403D is a straight-tooth planetary gearbox in a 60 mm diameter housing, giving a 32:1 reduction ratio. That ratio determines the speed-torque trade-off at the output shaft — for a given motor speed, the output turns 32 times slower but delivers 32 times the torque, minus the gear train losses. Continuous output torque is 44 N.m, with a maximum intermittent peak of 70 N.m. Efficiency is listed at 94 %, meaning 6 % of the input power is lost as heat in the gear mesh and bearings. For a motion profile that runs near continuous torque, that heat has to be dissipated through the black anodized aluminium housing — the 60 mm diameter and free-air mounting position (any position allowed) set the thermal boundary.
Service life and load limits — planning the maintenance interval
Rated service life is 30,000 hours at 100 rpm output speed and 30 °C ambient. That is the baseline for the continuous torque rating of 44 N.m and the corresponding axial and radial force limits: 450 N axial (Fa) and 340 N radial (Fr) at mid-shaft, both at 100 rpm, 30 °C, for the full 30,000-hour life. If the application needs higher force capacity for a shorter life, the gearbox can handle 600 N axial and 500 N radial for a 10,000-hour service window at the same speed and temperature. The lubricant is filled for life — no periodic oil change is scheduled, which simplifies MRO stock for the line. The torsional rigidity is 2.5 N.m/arcmin — a measure of how much the output shaft twists under load. For positioning axes that hold a repeatable stop, this stiffness number plus the 25 arc.min maximum backlash determine the lost motion the controller has to compensate for.
Mounting, sealing, and environmental fit
The gearbox mounts in any position — horizontal, vertical shaft-up, or shaft-down — which simplifies integration into a machine frame or a motor-gearbox assembly. The housing is black anodized aluminium, the shaft is C45 carbon steel, and the shaft output seal carries an IP54 rating, meaning it is protected against dust ingress and splashing water from any direction. Noise level at no-load, measured at 1 m, is 58 dB — roughly the level of a quiet office. In a production line, the gearbox noise will be masked by the motor fan and the driven load, but for a clean-room or lab-adjacent install, this is a quiet-running unit.
